Detailed Description

Regularized Heaviside function.

Can be used instead of mesh_im_level_set in assemblies. It's more stable, as it never fails in comparison to Delauney method (used inside mesh_im_level_set), but less accurate, as it has a transition zone from 1 to 0 of epsilon width. The idea is taken from one of the articles of Ted Belytschko on XFem
