The MEMS model problem

Please login with a confirmed email address before reporting spam

Hi,


I have several questions about the MEMS model and the general use of COMSOL.

I try to build a similar model as the MEMS tutorial example,However, it has a problem about
failed to find a solution for the initial parameter. Does that means I lost BCs? furthermore, I did not define BCs for the bottom part as the tutorial model. in the tutorial, it does not define the BCs for the BASE.

Moreover, when I use the electromechanics model, do I need to define every boundary? some BCs are not known, how could I define them?

cheers,

One more thing, if I use the domain to define some parts, do I need to provide the BCs for the same parts? Or the defining domains include the BCs?
