Moving mesh in shell geometry
 

Hi All,
I have a geometry containing a "shell" with 10 micron thickness. I need to simulate the particle transport. Is it possible to use moving mesh only in the shell part not in the whole geometry? The mesh movement will be opposite of the air flow.

I haven't used dynamic mesh in my simulation.

I am badly looking for some help regarding this problem.

Thanks in advance for your help.

Regards,
S. I.
