Hi,
Sir i'm new to COMSOL... Trying out differential pressure sensor... How to give different pressure input to the both side of the diaphragm? Is it possible?

Hi
How do you define your differentil pressure ?
Do you know the total presure on both sides, or of one side plus the difference?
You can write "p0" for one side and "p_tot - p0" for the other BC on the other side. In COMSOl, most entries accept full equations and even linked expresions also to dependent variables. But such cases might make your model highly non linear, which can give you convergence issues, and require further solver tweaking ;)

Good luck
