Which solver for time dependent : Electromagnetic Waves + Solid Mechanics

Dear all,

I am faced with a tricky problem for me, on which I cannot find a solution in the documentation. My model is representing a polymer that, subjected to some laser beam, expands in illuminanted area. So the geometry is changing with time : at t=0, the light is more intense in some places. t+1 the polymer deforms, and so induce a different light absorption pattern.

I thus have RF + Solid mechanics + Moving mesh modules. If I run a frequency analysis on the RF, I see the instensity of light being absorbed through the polymer. Then, if I run a stationnary study on the object, it deforms accordingly.

But both studies are not coupled, and I need to run 10 or more (who knows) studies like that (frenquency then stationnary) to get an idea of the real stationnary state.

My question is : is there a way to couple EMW and a moving structure with some study type? I discovered the "Frequency Stationnary" one, but it's only used with Joule heating, which is not the case here.

[Edit] : I read that : www.comsol.com/community/forums/general/thread/20275/ but couldn't find any positive answers.
