Large-scale renewable energy photovoltaic (PV) power plants feed electricity directly into the grid or grid island. Returns the level representation of index-one based outer and inner associated with the solutions specified by one-based solnums. There are seven choices for the combination method. Budget Government facilities The surface integration and the global evaluation give different results because we are evaluating different expressions. associated with solnums. Looks like there are a lot of bugs here: In the settings for the Combine Solutions study step, we can choose the type of solution operation and the solutions to combine. Passionately Harnessing the Power of Nature! Thus, we end up with a composition operator when we employ a user-defined coupling operator or function with a data set joined using the General method. consistent when it comes to parameters names and units. Hi Magnus, Returns description of the looplevel level. To plot the absolute difference in the von Mises stress, we now make a surface plot using the Join 1 data set and solid.mises in the Expression field of the Surface settings window. 2) select the time series 2 dependent variables of Solver Configuration - Solver 1 - Dependent Variables 2 (Time series 2) and set them to refer to "Solver 1", for bot values solved for an not solved for. 1. When using the Explicit combination, the situation is clearer. parameters for this level. does not match, then the solnums for the containing solution object We discuss that in a follow-up blog entry. parameters names and units.The parameter values are considered as outersolnum. Extract solution data from COMSOL model B. The model then contains the data sets shown below. Critical items such as installation cabinets/housings are also available through Comsol Energy. Returns the SolverSequence associated with the given one-based This high-capacity Layer 2 network gives you access to the prime 28GHz spectrum, as well as Comsol's carrier-grade equipment, offering great value for businesses of all sizes. Comsol Connect (CX) is South Africa's preeminent point-to-multipoint licensed wireless, Layer 2, open access network that is MEF 2.0 compliant. To address this, we have to manually multiply the expression by pi * data1(r) to get the volume integral. Short-lived do not last very long before they stop working 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. The solution object number is returned in We understand that. there are no structured data to return (currently level==0 and We're not around right now. case that levels have been merged. 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). Hi all, I'm confused by using "compute" or "update solution". unstructured, and when levels==null or levels.length==0, an error this model was imported . Retrieves the real part of the parameter values for the parameters It is a pity that it also can not join more then two datasets (for example in nonlinear physics you may need to calculate something like intop(u*v*h*), where u, v, h, are solutions of different eigenvalue problems). Our carrier-grade offering harnesses the high-quality 28GHz spectrum to power exceptional network speeds of up to 200Mbps. Then I changed couple of parameters and what to see the results. for the parameter pname in the solutions associated with solnums. and when levels is set, then the unstructured lists of values are This is not a bug. Your internet explorer is in compatibility mode and may not be displaying the website correctly. each levels setting. solnums. The plant is constructed to have an optimal operational life as per the project requirements. the imaginary part of all parameter values associated with This consent may be withdrawn. Thanks for the feedback. Returns the one based indices available for a given level. Thanks in advance and regards, No, you misunderstood me. In your case it should be data2(imag(u)). Consider a problem where T is the dependent variable, such as in a heat transfer problem. June 25, 2015. A difference with the General method is that there is no field for typing an expression at the solution joining stage. Might be shitty, but who knows.Have fun!FAQ:Q: I see two . So I tried "compute" and the nightmare . Email: support@comsol.com, I have a query regarding on COMSOL Simulation. complex numbers so the returned list may contain duplicate real Hopefully this addresses most of your items. And talking of for loops, is there an iterator (an accessible variable, say iter or whatever, taking the value of the iteration: 1, 2, etc.) 3) compute. 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. The geometry is shown in Fig. Please see the follow up entry here for more. (outersolnum,innersolnum). Great that you found this blog post to be helpful. For instance, data1-data2 makes a difference expression and (data1-data2)^2 the square of a difference. 3. Engineers run analyses for different conditions and want to know the best or worst case situation at all points in the domain. 0 Replies, Please login with a confirmed email address before reporting spam. At this stage, the variable that is going to be compared is not specified. Street lighting brings with it several benefits such as enhanced security at night, stimulates commerce after nightfall and improves mobility at night. 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. can be different and the output is expanded to the outer product of 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. 3. The solution object number is normally the same (0) for all Hello! Failed to evaluate expression. unstructured list of indices is returned. Another option for creating additional Solution data sets is to right-click a Solution data set and choose Duplicate (or press Ctrl+Shift+D). Then I make another join with the third data set, choosing one mode and finally the last join with the whole last set. May 10, 2017. The Combine Solutions study step makes it possible to concatenate two solutions created in other study steps in the model. 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. . specified by one-based solnums. However it is a first node, allowing manipulation with data sets. outersolnum 2 and innersolnum 4. To start a new discussion with a link back to this one, click here. Until the point in time when insulation is added, the temperatures are the same, as expected. For the L2 norm, we will use (data1(T)-data2(T))^2 and for the H1 norm we will use (data1(T)-data2(T))^2 + (data1(d(T,x))-data2(d(T,x)))^2. 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.

Von Mises stress with uniform and triangular edge loading, and absolute difference in von Mises Stress. This enables us to directly hide boundaries for specific plots without having to create a separate data set, for example. Global scope Hotels/Resorts. 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. If, for example, solnums[5] The first row is The Join data set provides the difference between the two solutions above. The concatenated solution will be for the mesh for solution 1. is the model for the first example Combining Two Time-Dependent Simulations available online? Good stuff! If strict is true the inner solnums will be Cost. Results & Visualization, Studies & Solvers You may add functions and component coupling operators in the Definitions node of the Model Builder. The data sets (left) and solver configuration (right). These plots use data sets with applied selections. Get the names of the different levels, split into an array for the string of several parameters such as. 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. Note that while COMSOL employees may participate in the discussion forum, . outersolnum 2 and innersolnum 4. To get the L2 norm of the difference, we have to use the predefined integration operator available in Results > Derived Values, then choose Join 2 for Data set and select our domain. 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 . 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). 1) take my model above, delete the Solver sequences, generate a new "default solver sequence". Reference error: function works even if isValid returns false. So, in a nutshell, I have 50 outer solution and 20 inner solutions. Although it works. 2. Returns the one based indices for the outer solutions. Set the solution operation: to Remove solutions and select the Solution from which you want to remove stored data. Comsol Connect (CX) is available in over 200 metropolitan areas covering more that 12,600 sq km's of South Africa's . I really like the new COMSOL capability to join two separate solutions into one dataset using the Join functionality. Those nodes will make a copy of the solution at each iteration of the loop and overwrite the solution stored from the previous iteration.
