how do i create a crater (upside down hollow dome) and include it as a geometry in a PDE model?

thank you helpers

Try using 3-D geometry from a point cloud. Your dome cannot have zero thickness for a 3-D model.

Would it be possible to assign different bc to different parts of the surface? Is there a library containing some sorts of geometries? Thank you

[Alan Weiss]

There is no library of geometries that I am aware of. If you find some STL files that suit you somewhere, you can import them.

You can set boundary conditions to be functions of position, so they can work however you like. That said, it is often best if you have a portion of the geometry to have a different face ID to make this work more easily, but I do not know how you can control that aspect of geometry creation. Boundary condition specification is described here.
