These tools are generally applicable and useful in many cases beyond what we have shown here. We can achieve such a combined solution using the Combine Solutions study step, which is new in version 5.3 of COMSOL Multiphysics. If we have data1 + data2 under Expression in the Join settings window, we can use it either with u, which returns data1(u) + data2(u), or with v, which returns data1(v) + data2(v). Without Limits. Doing something a little different from lyrics in my spare time. Banks/financial institutions Might be shitty, but who knows.Have fun!FAQ:Q: I see two . 1. To construct the maximum temperature envelop, we make a joint data set Join 1 from the two solutions using the General method and max(data1,data2) for the expression. values are considered as complex numbers so the returned list may It is deliberate. solnums. (without duplicates) for the parameter pname in the solutions Vulnerable often vandalized for their parts (batteries and solar panels) parameter names returned by getPNames(solnums). According to Saint-Venants Principle, the difference in the solution should diminish as you go further from the loaded edge. Dear Abdallah, array will be an array containing all parameter names associated with number outersolnum. The following inequality specified by one-based solnums. One option is to use a parametric sweep or load case to investigate the stresses and deflections in the wrench for various forces applied as a boundary load at the end of the wrench. We can also use a Join data set to combine solutions from two different Solution data sets (as a difference, for example). 3) compute. Variable: r Dedicated solutions providing 48 volts for powering telecoms infrastructure are available through Comsol Energy. Battery technology continues to advance, bringing both cost and performance benefits. Here, d(T,x) is the derivative of T with respect to x, which is a predefined operator in COMSOL Multiphysics. case that levels have been merged.

The cylinder lies horizontally along the y-axis at mid-height and in the middle in the x direction in a cubic solution domain that is 10 km on a side.The rectangular prisms along all of the outer faces, edges, and . In addition, we add the following data sets: The following plot shows the temperature versus time for the concatenated solution, where heating is replaced by insulation after 190 s, and the continuous solution, where the heating continues during the time span of the entire simulation. Set the solution operation: to Remove solutions and select the Solution from which you want to remove stored data. If i have two solutions, one for optical modes and the other for accostical modes, at first i was intrested in doing surface integration with one optical mode and one accoustical mode so i used the join data option but now i am intrested in two optical modes and one accoustical mode so jow can i join 3 data solutions please? The Join Feature in COMSOL Multiphysics. When the format is unstructured, and when levels==null or Thanks Tanchiky!https://ta. If we choose Join 2 for Data set and intop1(T) for Expression in Results > Derived Values > Global Evaluation, will we get the L2-norm of the difference between the two base solutions? 4. Which one you want to use depends on what you are doing. In the Join settings window, you need to make two choices: which solutions to combine . Please see below for answers to your three questions: 1. Right beneath Data 2, you can configure the combination method. Thanks in advance and regards, array will be an array containing all units associated with it is not available in the prepared expression. Another case where it is of interest to manage multiple solutions is when we run a simulation multiple times (with some variation in the model or settings) and want to postprocess and analyze the results from each run. But lets see what happens if the loads direction is reversed so that the wrench is pulled upward (instead of pressed downward as it is in the example model from the Application Gallery). Returns all parameter units for the level. then the 5th entry in the return array will be an array containing This function works even if isValid returns false. Learn more about Join data sets in this blog post: To get started with managing multiple solutions, download the tutorial models featured in this blog post: See other new features and functionality in COMSOL Multiphysics version 5.3 on the. How Large of a Model Can You Solve with COMSOL? They are equivalent to using the General method with data1-data2, abs(data1-data2), data1*data2, data1/data2 and data1 + data2 for Expression. Dedicated solutions providing 48 volts for powering telecoms infrastructure are available through Comsol Energy. Then, we create a joint solution Join 1 using the General combination with abs(data1-data2) in the Expression field as shown in the above figure. For instance, we can use a duplicated data set to add a Selection node, if it is of interest to postprocess the solution in only a part of the model geometry. solution numbers. I will pass your comment about the all-all combination to the development team. These two loads are statically equivalent. It would be perfect if Combined Solutions could accept ANY number of (time) steps. If you're looking for ways to manage multiple solutions, version 5.3 of the COMSOL Multiphysics software offers several new tools for doing so. Returns the index-zero based solution object number and the index-zero if you try to join both with all solutions it just gives out an error number outersolnum. The Combine Solution node together with a Solution Store inside a for-loop should be able to accumulate all the solutions. Hi, I'm a relatively new user in COMSOL. Actually, I found the issue today. . The section Using Operators on Joined Data Sets explains the order of operation. in COMSOL Multiphysics wasnt possible to use a transient multi solution as input under Values of variables not solved for by selecting time: all yet. There are two types of multi-solutions: * Multi-parametric solutions (for example, having t and other parameters as coming from Time-Parametric solutions). parameters names and units.The parameter values are considered as You determine the base data sets under the Data 1 and Data 2 sections. Sounds a bit cumbersome :- ) That can be done only with some external java or matlab, but what about time on one join redefinition? These examples illustrate some of the flexible and powerful options that are available in version 5.3 of the COMSOL Multiphysics software. The first row is I am working on the energy pile performance (the energy pile, also called heat exchanger pile, is a pile equipped with individual or several pipe circuits in order to enable exchange of heat with the surrounding soil). treated as level-tuples. is there any tutorial available for multiple steps and solution management? If you have problems getting your model to run, I recommend that you contact the COMSOL support team. Hopefully this addresses most of your items. Returns the maximum number of inner solutions for the given outer consistent when it comes to parameters names and units. http://www.comsol.com/blogs/solution-joining-parametric-eigenfrequency-time-dependent-problems/, Multiscale Modeling in High-Frequency Electromagnetics.

Suppose we enter (data1-data2)^2 in the Expression field in the Join settings window and named the new data set Join 1. These solutions range from battery backup solutions to standalone PV with integrated battery storage, and finally to hybrid systems that augment the PV system with either mains or generator supplied power. Solution to the problem: The best way of evaluating a point's data is by using COMSOL live link with MATLB. Some of these may be a the number of levels. Email: support@comsol.com, I have a query regarding on COMSOL Simulation. The cost for this course is $800 per person. Some possible scenarios include comparing the effect of different load or parameter configurations, and enveloping results to find the worst or best case at each point of the domain. solutions specified by one-based solnums. Is that a bug or is that meant to be? level < getMaxLevels()-1 this is just the values/tuples of the Comsol Energy offers a model where we operate and maintain the PV plant as an Independent Power Producer (IPP). Finally, use T for Expression. Dear Temesgen, Figure 6: Closed surface excluding the charge The electric flux density at some boundary surfaces of the closed structure is presented . The plant is constructed to have an optimal operational life as per the project requirements. Going back to the temperature envelop example, we needed two joint data sets to make the maximum and minimum temperature envelops using the General method. To demonstrate the use of solution joining using the General method, we will consider two modeling examples. In this example, a 2D plane stress model of a membrane with a thickness of 0.1 meters is alternately loaded by a uniformly distributed load of 10 MN/m along the right end and a triangular load at the same edge with a maximum intensity of 20 MN/m at the center and vanishing at the ends. If you still need help with COMSOL and have an on-subscription license, please visit our Support Center for help. Returns the index-zero based solution object number for the time value. I am using COMSOL 4.1. As an alternative to the concatenation of solutions (time-dependent or parametric solutions, for example), it is also possible to use summations to combine solutions (such as creating a solution that is the sum of various eigenmodes). is returned. returned. The geometry is shown in Fig. isValid returns false. For The extension made in the blog example is not available online, but the model that its based on is available here, as noted in the blog: https://www.comsol.com/model/axisymmetric-transient-heat-transfer-267. Finally, check your initials conditions, by hitting the node Solve . Comsol Connect (CX) is South Africa's preeminent point-to-multipoint licensed wireless, Layer 2, open access network that is MEF 2.0 compliant. If strict is true the inner solnums will be list of solnums is assumed to be consistent when it comes to In COMSOL software, the time dependent study with time-dependent solver, I want compare the value of the solution of a variable at the current timestep and that at the last timestep. All the solver settings appear to be the same in both models. each solution. So I have to make a join of first pair of sets, choosing manually two of 2000 modes. If you're looking for ways to manage multiple solutions, version 5.3 of the COMSOL Multiphysics software offers several new tools for doing so.

Those nodes will make a copy of the solution at each iteration of the loop and overwrite the solution stored from the previous iteration. the case when there is more than one. When a mutually satisfactory PPA is signed, Comsol Energy also offers to provide the necessary financing for the realization of the project through our third-party financing partners. Hi all, I'm confused by using "compute" or "update solution". COMSOL Multiphysics version 5.1 includes a Previous Solution operator within time-dependent studies. solution numbers. Hi Magnus, Not yet, but it has been suggested before to introduce such a variable. The temperature envelop shows the extreme temperature values at each point under any circumstance. Then that data set now becomes available for another joining operation with the third data set. When you opt for this method, COMSOL Multiphysics makes two new operators, data1 and data2, which can be used to access quantities from the first and second data set, respectively. 3. outersolnum 2 and innersolnum 4. For these study types, solution joining can be used to evaluate some useful and interesting quantities. The funny thing is that data2(with(n,u)) works even if you have chosen only one solution to join. 3. In the Join settings window, you need to make two choices: which solutions to combine and how to combine them. The Solar Glow range uses state-of-the-art LED lighting. I know that that means that likely my boundary conditions are screwed up, but I'm not finding any discrepancies between my model and the boundary conditions of the comsol model? Im doing Solar PV Cell with different structures by using a 2D model physics & I used electromagnetic waves and frequency domain, study I have used frequency domain, as result of that I get reflectance data for different wavelengths and after I tried to design the si_solar_cell_1D model as per the COMSOL design instruction procedure after simulated, I get the I-V and P-V Curve of solar cell. Thanks for your clarification. It helped a lot. In the plot below, you can see the joining operation and the result envelop together with the results from the two base cases: Thank you. The number of rows is the same as the number of unstructured, and when levels==null or levels.length==0, an error The simultaneous use of two boundary conditions (for grounds domain and piles domain) is incorrect, because it causes a meaningless temperature interference. parameters for this level. Retrieves a list of one-based tuples (outersolnum, innersolnum) for listed if standards is not an option). If, for example, solnums[5] corresponds to the tuple (2,4), About the COMSOL Product Suite. So, in a nutshell, I have 50 outer solution and 20 inner solutions. The construction data1(data1(data2(with(n,u)))) also does not look time-optimized. To combine the two time-dependent simulations, a Combine Solutions study step provides a concatenation of the first and second study step. Greetings, Kant. However, five of those can be taken as special cases of the other two options. You may add functions and component coupling operators in the Definitions node of the Model Builder. Get the units for the subset of parameters that are looped by an outer Is this a feature intended? Comsol Energy offers a range of different PV systems that are customized to the specific needs of our clients. In essence, we are constructing an operator that can later be used with any quantity defined in both of the original base solutions. Do I need to rerun the compute for the combined study to be effective? The surface integration and the global evaluation give different results because we are evaluating different expressions. that we can use, for instance in the time steps (like iter*t)? Get the subset of parameter names that are looped by an outer The number of rows of the returned data is equal to Please see the follow up entry here for more. The problem is, if I rightclick study and hit compute, it thinks fora couple of minutes and gives me the error, "Failed to find a solution: Divergence of the linear .

If we want to plot the minimum temperature envelop, we have to add a new joint data set using min(data1,data2) in the Join settings window. The Join settings window. solnums. In the Settings window for the Combine Solutions study step, we specify the study steps to concatenate. When integrated with a PV array or just connected to the grid, energy storage solutions allow constant or at least predictable power for electrical devices. Exploiting Hardware Parallelism with COMSOL Batch Sweeps. You can fix this by pressing 'F12' on your keyboard, Selecting 'Document Mode' and choosing 'standards' (or the latest version The innersolnum - Inner solution numbers. 3. In this blog post we have focused on joining stationary solutions with no parametric sweeps. Thanks for the feedback. Yes, there is a link in the blog post that takes you to the Application Gallery, where the Axisymmetric Transient Heat Transfer example model is available: https://www.comsol.com/model/axisymmetric-transient-heat-transfer-267. Business continuity is imperative. These are Failed to evaluate expression. You can then either explicitly or implicitly remove or save data from the model, as shown in the screenshots below. In the settings for the Combine Solutions study step, we can choose the type of solution operation and the solutions to combine. By providing your email address, you consent to receive emails from COMSOL AB and its affiliates about the COMSOL Blog, and agree that COMSOL may process your information according to its Privacy Policy. This mathematical expression contains the variables z and t. But unfortunately, only a specified time (by default, t=0) is used in time-dependent analysis and the time range defined for the expression is not considered. The same is true for eigenfrequency and frequency domain studies. Keep in mind that the solution time-step can different from the steps COMSOL record the solution. The data sets and corresponding solver configuration are shown below. Get the number of levels in this solution. The order of the parameter values is The COMSOL Multiphysics software brings a user interface and experience that is always the same, regardless of engineering application and physics phenomena.. Add-on modules provide specialized functionality for electromagnetics, structural mechanics, acoustics, fluid flow, heat transfer, and chemical engineering. As pointed out above, when using the General method we also get an operator. When plotting the results of the combined solutions, it looks like the mesh for solution 2 is lost, and all the results are with respect to the mesh for solution 1. I really like the new COMSOL capability to join two separate solutions into one dataset using the Join functionality. Provide constant power regardless of time of day or weather. Then after integration I will obtain 1000 interaction values and will have to manually change the modes in all joins. When we then recompute with changes to the model or solver settings, the new solution is available through the original Solution data set, so that we can postprocess and evaluate both solutions by pointing to one of the two data sets (we can extend this approach to create additional solutions). Retrieves the imaginary part of the parameter values for the We understand that. Short-lived do not last very long before they stop working Online Support Center: https://www.comsol.com/support Commercial enterprises Existing solar lamp solutions are typically: Low power do not give enough illumination Operation (float charge, deep cycle, high temperature, high C rate) case when there is more than one. Returns the one based inner solution numbers for the outer solution there are no structured data to return (currently level==0 and Hello, I want to ask, if there is a way to get and save the solution when I cancel/abort the simulation by myself. The top data set refers to the output from the third and final time-dependent study step. Retrieves the imaginary part of the parameter values for the Comsol provides an end-to-end open access solution that is ideal for smart city infrastructure such as water, electricity and manhole cover monitoring, as well as smart agriculture, conservation, tracking and logistics, to name a few. innersolnum, but can vary for so called multi-solutions Retrieves parameter names for the parameters associated with the If there are no outersolnum. Concatenation is the most common (and the default) option: You can use it to join (concatenate) two time-dependent studies, for example, where one covers [t0, , t1] and the other [t1, , t2] so that you get one time-dependent solution for the entire time span [t0, , t2]. 2. The study steps for a combined solution and a reference solution with only heating. Retrieves units for the parameters associated with the solutions June 25, 2015. Temperature difference between the two solutions. (attached). The wrench models data sets for comparing the two cases and for postprocessing using only the wrench and only the bolt. In the second case, the temperature is flipped, going from 400 K at the left end to 300 K at the right end. In engineering analysis, the need to compare solutions obtained under different circumstances frequently arises. When using the ribbon (or menu if youre running Mac OS or Linux), the command is Results > More Data Sets > Base Data Sets > Join. COMSOL is dedicated to providing comprehensive, cost-effective solutions that enables each of its customers to achieve their objectives and have a competitive edge in their respective markets.. COMSOL's founding members have over 40 years Telecommunications experience, and a proven track record of success in the CALA region for building and selling data networks. The WITH operator works only within one solution, so I have to use join if I need to combine different modes from three different data sets. Using a Join data set, we can plot the temperature difference between the two solutions. Then I changed couple of parameters and what to see the results. As expected, the temperature increase slows down when insulation is added. After computing an initial instance of the model, we right-click the Solver Configurations node in the study and choose Create Solution Copy to make a Solution Copy solution and a corresponding data set available for our current solution (pointing to the Solution Copy solution node under Solver Configurations). For example, if you have a parametric sweep with 2 variables, its cumbersome to compare different stages with with, in matlab its simpler. The figures below show how the difference of the integrals and the integral of the difference are evaluated on an explicitly joined data set Join 3. Different battery technologies suit different applications. The maximal number of levels any solution can have. However it is a first node, allowing manipulation with data sets. Fig. In this context, an outer solution is a parametric sweep solution over a parameter such as a geometric dimension. Thanks for your reply, I need a clarification on this topic., The Combine Solutions study step makes it possible to concatenate two solutions created in other study steps in the model. Traditional Lead-acid or . COMSOL Moderator. To start a new discussion with a link back to this one, click here.
