Hi!
In Comsol u can have multiple study. I have a specific case: a two physics model which first has a periodic condition and second has a time domain condition. First physic is independent so it can be solved lonely (time period is 20 s), but the second is dependent on the first physic (study time rang 4000s). The simultaneously study is very time consuming. Is any way to solve first physic and then use it for second but as a periodic load?
Is the "periodic condition", a boundary condition or something else?
Either way, we can utilize result of Study1 with withsol() function.
Edit: Would recommend usage of withsol() postprocessing. A trial to cross check with simultaneous study using small period can be helpful.
If the periodic condition is in the first physics, in the transient study of your second physics you can simply select "user controlled" from "values of variables not solved for" and you give as an input the last computational time of the previous study.

Mostafa Jafari So you have full 3D in your second study, correct? In that case you would probably need to use something like Linear or General Extrusion operators to map from the periodic geometry to the full one.
