Surface Meshing
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.
