I am attempting to mesh a simulation of a very thin conductor (0.1 um) with lateral dimensions in the range of 100's of um (for stationary COMSOL AC/DC magnetic and electric fields simulation).
Whenever I attempt to generate a tetrahedral mesh, I get a "face is much smaller than the specificed minimum element size" warning; but if I manually set the minimum element size to 0.1 um the geometry becomes excessively meshed.
It seems like this issue could be solved by a hexahedral mesh option but I can't seem to find that mesh option in COMSOL 5.3
