2 stationary studies within one study

Please login with a confirmed email address before reporting spam

I am interested in solving two stationary problems on the same geometry within one study. The only difference between the two problems is that the flux boundary condition is applied to different surfaces. The reason I would like them to be part of one study is so that I can use the results from both the problems and do optimization. Essentially the objective function that I would setup would involve results from both the problems.

Both problems have a time scale of 10 picoseconds and hence they reach steady state very quickly. I would prefer not to run a transient problem with the switch in the boundary conditions taking place after steady state is reached for each one of them.

I would greatly appreciate any help.

Thanks

Hi

probably the easiest is to set 2 stationary solver nodes under the same study node, for each you turn on and off the desired boundary loads (or you have grouped them in load groups) and then you rune both, COMSOL will normally add a Store solution node in the solver sequence and therefore you can access both data sets for your postprocessing

Good luck
