Surface Meshing

Summary

Kuprat, A., 2000. Modeling microstructure evolution using gradient-weighted moving finite elements. SIAM Journal of Scientific Computing 22, 535-560.

The Moving Finite Element (MFE) algorithm is based on Kuprat's work on Gradient Weighted Moving Finite Element method [SIAM]. A conformal triangular surface mesh represents the grain boundary network. The curvature at each node is computed and used as the driving force for nodal motion. Additional forces are computed based on element quality. The user can choose a balance between the curvature and element quality forces to find a compromise between smoothness and final element quality. Certain node types can be constrained in their motion. Nodes on an external surface can be constrained to move in the plane of the surface. Quad point nodes can be prevented from moving.
