Hi I am planning to use COMSOL for modeling Chemical Vapor Deposition. I am using Diffusion Reaction model to model my process. But the tricky part is moving the boundary as the deposition progresses. I am planning to use Deformed mesh (ALE) mode for this. But I haven't been able to run my simulation successfully. I think I am messing up in the ALE part. I have read the manual. But that hasn't helped. So, I have decided to get a hang of ALE first by doing simple simulations. I tried to simulate a cylinder which contracts with a constant velocity. That is the simple possible case I could imagine. I did not include any physics. But I couldn't make any sense of the result. Can you please help me out ? Is there any simple ALE-only example somewhere. Can you send me the file ?

Thanks in advance,
Sanket

When I run the simulation I get back the initial geometry ? How can I show the boundary movement ? Can somebody please help me out ?

Thanks
