This is for COMSOL 5.2, but should be similar for 4.2: Create the stationary study. The "Values for dependent values" in study step settings should be set to the default ("Physics-controlled" in 5.2). This will use the initial conditions you specified in your physics setting (usually 0 is used in the physics settings). Release Notes C OMSOL Multiphysics version 4.3a contains many new functions and additions to the COMSOL product suite. These Release Notes provide information regarding new functionality in existing products. We have strived to achieve backward compatibility with the previous version and to include all functionality that is available there.

Finite Element Convergence Studies of a Time-Dependent Test Problem Using COMSOL 5.1 Kourosh M. Kalayeh ([email protected]) Department of Mechanical Engineering, University of Maryland, Baltimore County To modify how the time-stepping methods select the time steps, choose an option from the Steps taken by solver list. Select: • 'Free' to let the time-stepping method choose time steps freely. The times specified in the Times field in the General section are not considered when a time step is chosen. If you want to output the results at the exact timesteps taken by the solver, go to the Time-Dependent Solver settings, Output section, and set the Times to store: to Steps taken by solver, as shown below. Be aware that this option may generate a lot of output data.

A consequence of this COMSOL, Two different steps or two studies ? ... and two "Time Dependent" study (sol1(for actd) & sol2(for actd2)) and in 3D I have two regions with different initial values (numerical values for ... Study Settings The study always consists of two steps, first, a Phase initialization step initializes the level set or phase field variable such that it is smoothly varying everywhere. Next, a Time Dependent step simultaneously solves the Navier-Stokes equations and the Level Set or Phase Field equation.

Yes you can do that. It is very useful. Just make sure to set 'use parametric solver' under the Parametric Sweep > Study Extensions to 'OFF'. Changing this setting should not be necessary since the "Automatic" option looks for parameters being used in geometry and mesh settings. If any such use is detected, the parametric solver will not be used. Yes you can do that. It is very useful. Just make sure to set 'use parametric solver' under the Parametric Sweep > Study Extensions to 'OFF'. Changing this setting should not be necessary since the "Automatic" option looks for parameters being used in geometry and mesh settings. If any such use is detected, the parametric solver will not be used. This is done by using two Studies. Study 1 is used to compute the curvilinear coordinates and Study 2 is used for the heat transfer in solids. These are the settings for Study 1: The Study 1 settings. The Study 2 settings are similar, but here we also need to define what to do with values of variables not solved for. $\begingroup$ Your question is not well posed: before asking for the time step you should ask for the time integration method used to solve your equations. (Sorry I have no idea of which integration schemes are implemented in comsol, and I doubt that there is a one-size-fits-all one used by default.)

Use the COMSOL Desktop to get your first model implemented using the COMSOL Java API. Set-up the model using the graphical user interface, then save the model as a M-file. To proceed go to the File menu and select Save as M-file. This generates a M-function that you can run using COMSOL with MATLAB. † Study the LiveLink for MATLAB Model Library Top nine hints for working with Comsol. From Site.
