Boundary error

Please login with a confirmed email address before reporting spam

Hello,

I'm trying to calculate the electric field distortion produced by a water droplet, which I simulate as a half sphere.

When depositing the droplet on flat surfaces, like the one shown on the attached picture, I just set the center of the sphere to be on the surface. It works fine, I set the half sphere buried on the insulator to be the same material of the insulator and the half sphere outside of the insulator to be water.

But when I try to do the same trick on a round surface, on the shaft of the insulator, it fails with the following error:


ERROR
-----
A problem occurred when building mesh feature 'Free Tetrahedral 1'.
Failed to generate mesh for domain.
- Domain: 1
Failed to respect boundary element edge on geometry face.
- Face: 86
- x-coordinate: 25.5097
- y-coordinate: 1.24467
- z-coordinate: 407.117
Internal error in boundary respecting.
Error in multiphysics compilation.


WARNING
-------
Low minimum element quality


What can I do?


Thanks

Diego Puertas


Edit: just found out how to decrease the file size, so I'm attaching the model file too.
