HI
How to model a 3D part in a 2D shell geometry and apply 2D physics ? I have a simple geometry of a very thin composites part which i apply vacuum in the borders and extract pressure values, the geometry is an hemisphere in the middle of square and i wanna apply 2D physics model, the issue is that i couldn't do it by selecting the 2D space dimensions and when i tried to extract the surface from the 3D model that export it the the 2D it didn't work .
Best regards

Hello Ayyoub,
Midsurfacing (i.e. turning a thin solid object into its midsurface) is a capability found in the Design Module: www.comsol.com/design-module .
Regarding solving a 2D equation on a manifold in 3D space, there are such formulations implemented in COMSOL for various physics, including solid mechanics, diffusion, electricity, etc. An example is found here: www.comsol.com/model/shell-diffusion-in-a-tank-222
Best regards,
Jeff
