I am trying to simulate a simple model (ver 5.1): a silicon plate and a hollow space inside where air can be found (purple block), with atmospheric pressure being applied. I want a vaccum around the silicon (Surface-pressure of 5 mbar around the 6 surfaces of the silicon block). Thereby, due to the pressure difference, the top and bottom surface of the silicon will deform.
I am trying to set the B.C.'s, but there are always errors. What do you think that I should set as B.C.'s?
Surface load for the Si block? But for the air area inside? I just want it that the pressure difference between the air (1 atm) and the outer vacuum (5 mbar), will deform the silicon.
I hope I was clear with the model description. I am also open to suggestions and ideas how to solve it.
Thank you a lot beforehand.
