I I am trying to simulate a problems that has three length scales, nm, um, and mm. For the nm and um length scales I am using the MoM and for the very large length scale am using the RL-GO solver. Are these length scales too disparate for the solver? I had to increase the extents of the problems but then ran into errors regarding mesh tolerance size. Do not really know how to correct this given the extents of the problem.
