I have tried and solved a few 2D plane stress problems successfully, but I am having no luck with even the most elementary 3D beam. The call to ToElementMesh stalls for ever and then I just have to force Mathematica to quit.

{a, b, c} = {5000., 400., 200.}
v = ImplicitRegion[0 <= x <= a && 0 <= y <= b && 0 <= z <= c, {x, y, z}]
emesh = ToElementMesh[v]

What am I doing wrong? Or is it because my student edition of Mathematica for Personal Use does not support 3D?

I have attached a screenshot of Mathematica alongside the performance view of TaskManager, in case it helps. The screen shot was taken several minutes after I started the ToElementMesh command; does not seem like the command is doing anything at all.

Thank you for your help.

By the way, I have version 12 (64 bit).
