Hello Everybody,
I tried to simulate a 3D problem in electrostatics and found the following warning message under meshing,"face is much smaller than the specified minimum element size". Please help me to infer from the same!!!
Thanks in advance.

Muthuraman,
This is a common warning in my experience. Note that warnings are not fatal to moving forward in your modeling work. Errors however need to be addressed.
The warning you received alerts you to the fact that your geometry has a very small face relative to your minimum element size (a Mesh setting). If you want to disregard this warning and would like it not to show up, simply decrease the minimum element size setting and re-mesh until the warning goes away.
Alternatively, you can heed the warning and consider doing defeaturing of your geometry using the CAD defeaturing functionality of the COMSOL Geometry node. The warning should tell you which face is the problem face.
Best regards,
