Hi,

i'm currently using the version 4.2a. i'm trying to model a capacitive pressure sensor. i downloaded a capactive pressure sensor from comsol website (for version 4.3) and it is working fine. in that model air is being used as a material for the reference cavity. i created my own model and when i use air as the material for the reference cavity, i have been asked to enter the young's modulus and poission ratio of the air. what is the reason behind it? can anyone please explain?
