[Insight-users] Adaptive Meshing for FEM - Registration

[Nicholas Tustison]

Hi Markus,

A straightforward conversion between an ITK mesh and a FEM mesh is  
non-existent.  I'm reworking the FEM mesh class now and maybe I'll  
come up with something but until then...

The current FEM framework allows for an external mesh to be brought  
into the FEM project but that, in addition to the default rectilinear  
mesh that is created when no external mesh is specified, is the  
extent of the current FEM library meshing capabilities.
