Error: Failed to generate mesh for domain, Intersecting face elements

Please login with a confirmed email address before reporting spam

Hello,

I am attempting to simulate the electric field of an imported CAD geometry (attached below) that includes a wire readout plane. My naive approach of generating a physics-defined mesh yields a long list of errors, due to supposed intersecting face elements and faces/edges that are shorter than the specified minimum element size. Most of the issues seem to occur where the small wires are attached to the board.

After going through some of the blogs and tutorials, I have made some attempts to separate the edges (using the Edge operation) and define an "Extremely fine" mesh for the wires, but I still run into the same issues down the road when I mesh the "Remaining" domains.

Could anybody please give a recipe for how to best tackle these issues? Is this better solved at the level of the CAD file or can I work within COMSOL?

Many thanks for any advice you can offer, Michael
