I am new to comsol community and I am facing a simulation of a membrane/wall deflection over a microfluidic channel. At this moment, I have a microfluidic channel which is formed by a domain filled with fluid (no wall thickness, just the path the fluid follows). At some point of the channel (rectangular cross section), I have a 200 micron layer which I would like to deflect upon mechanical load.
I have always simulated microfluidic chips being the chip as the domain where the fluid flows, not considering any wall thickness. It is now, that I want to simulate mechanical actuation over a 200micron thickness wall that I wonder how I should set the walls (thickness yes or no?). In addition to this, is it possible to do it with the basic functionalities of COMSOL multiphysics 5.4? Or should I get the specific structural mechanics or MEMS module?
Thanks in advance, Pablo
