While I am aware of adaptive meshing, I was looking to just assign the mesh density at the start because I'm already pretty confident in what I want the final state of the mesh to look like (the first figure in my post).  The extra expense of implementing adaptive meshing seemed unnecessary.  Its just that I wasn't sure exactly how small to make the final edge length.  The convergence study would be identifying the point of diminishing returns in simulation accuracy within the 10 um to 100 um edge length range, since I know there's no disk of divergence for these parameters.  If there is really no support for this kind of area-wise local refinement with a targeted edge length, I could fall back on NLAD routines, it just seems kind of wasteful from my perspective.  If there is any support for doing it in advance like I've outlined, please let me know!
