Comsol multiple studies You can have more than one study (each generating one or more solutions) for different scenarios using the same geometry and physics interface. The idea is that as the membrane moves upwards the capacitance will The main study step types — most of them available as a study in the Add Study window — are listed in Table 20-2. EDT Edgar J. Is there any possibility to start the calculation of the studies automatically? Like a command that tells Comsol "first you compute studie 1, then 2,. (1) multiple studies Study 1: Bolt pretension Study 2: Heat transfer in solid-Thermal expansion Study 3: Service load. aso" Thank you very much for your help! Best regards, Jul 4, 2024 · Hello! I am currently trying to simulate some acoustic streaming interactions on COMSOL 6. When we compute the study, the study steps create corresponding solvers and Solution Store nodes in the solver configuration and also solution data sets for analyzing the results from the solvers. mph -study std1 For other study steps, see the COMSOL Multiphysics Reference Manual. When you use separate studies you have to make more settings in the study node to point to the results in the preceding study. Additionally, we discuss Oct 7, 2016 · The model itself works without any failure but I have to start the computation for every study manually, what makes it pretty time consuming. Just check "Modify physics tree and variables for study step" in the Study Settings node and disable/enable appropriate boundary conditions in your stationary and time-dependentent studies. Feb 3, 2016 · In many cases i would like to just click on solve a second time to generate a second solution. 5 Replies Last Post Mar 17, 2014, 2:56 a. If you add a sequence under a physics interface component, all available study steps can be added to the sequence, but it is then not allowed to link to this component from an interface that does Nov 22, 2011 · Best practice for conditionaly switched boundary condition (simulations with multiple steps) Posted Nov 22, 2011, 6:03 a. A study containing a Parametric Sweep node can be run from the command line, for example by invoking. I don't mind having multiple studies in my models to be able to generate more solutions but it is very annoying that i can't duplicate the studies (without the solution set) especially when i have made some complex settings in the solver. 2 6 Replies Oct 1, 2012 · As of Comsol version 4. In postprocessing I would now like to "stitch" these two solutions together, so that instead of having to deal with two data sets sol1 and sol2 I just have one data set solComb that contains the combination of these consecutive two solutions. m. In this video, we provide a comprehensive overview of adding a study to your model, including how to choose and add studies, edit the study settings for multiple study types (using a thermal bracket tutorial model), and use the different parts of the COMSOL Desktop ® that provide information as your model is computing. Having loosely followed one of the example files, I first created a frequency dependent study (study 1) to solve for the acoustic field, and following that have a stationary study (study 2) to calculate the fluid field based off the results of study 1. Some studies require add-on modules, and these are listed in Table 20-3 (in that list, the submenu under Study Steps in the Study branches appears in parentheses for the study types that are available as individual study steps). The study step represents the next level of detail. Jun 10, 2018 · If the studies are not really connected to each other, I would suggest using two different studies, rather than study steps. You can perform such a sequential study using multiple study steps in a single study or using multiple studies in the same model: • The Add Study window is similar to the Select Study window accessed through The Model Wizard. It has the same studies available and is a quick way to add a study (or studies) to models. . It is only possible to add the study steps that the physics interface supports. However you choose to add a study, a study node is added to The Model Builder including a corresponding study step (for example, Stationary in Figure 20-1), and in some cases, additional study steps. Apr 16, 2019 · Hi. Feb 5, 2016 · Hey all, I have two consecutive time dependent studies and two solutions sol1 and sol2. Regards, Henrik----- It is sometimes useful to run one simulation for one aspect of a model and then use the output of the first simulation as input into a second simulation, covering a different aspect. mph -study std1 and in case of a distributed Parametic Sweep, for example by launching. 2 using the new acoustics module. In this way it is easy both to run each study individually, and also to run both at the same time. COMSOL batch -inputfile mymodel. Study 1 setting 1) Model configuration for study step Bolt pretension : Enable Heat transfer-thermal expansion : Disable Service load : Disable 2)Values of dependent variables In this video, we provide a comprehensive overview of adding a study to your model, including how to choose and add studies, edit the study settings for multiple study types (using a thermal bracket tutorial model), and use the different parts of the COMSOL Desktop ® that provide information as your model is computing. It is also easier to run the whole sequence at one go. There are also study 2 and study 3 nodes parallel to study 1 node. mph -outputfile out. EST Modeling Tools & Definitions, Parameters, Variables, & Functions, Studies & Solvers Version 4. Isn't the initial value of study 3 (under study 1) taken as the last step solution of study 2 (under study 1)? Are studies 2 and 3 (under study 1) solved totally separately? Feb 7, 2023 · 1) multiple studies 2) multiple steps. Then you add a third study of the type 'Empty study' and add two 'Study Reference' steps. At any time you can also add studies (see The Add Study Window). 3, you can define different boundary conditions per study, without changing the model tree. Kaiser Certified Consultant Apr 16, 2024 · Under study 1 there are 2 study reference nodes: study 2 and study 3. May 10, 2017 · In the settings for the Combine Solutions study step, we can choose the type of solution operation and the solutions to combine. Can anyone help me to figure out how to run multiple studies in COMSOL? I want to first compute the displacement of a membrane using temperature load and then find the capacitance between two electrodes using electrostatics. The data sets and Aug 6, 2019 · The main advantage of using multiple study steps is that initial conditions are automatically taken from the preceding step. COMSOL batch -nn 4 -nnhost 4 -inputfile mymodel. Jan 24, 2014 · I managed to script this task using the Matlab interface but it would be nice to have it done within COMSOL in order to run the study on our cluster. xogtwb smqxapb rzmz usyfgd nyiao bcmzr pzfgv bqps gscr gop qng ztagr lwol ynlnwkzg aqukso
