GAMMA moves the nodes of a boundary-surface mesh to follow a deforming CAD geometry, using graph-Laplacian motion for triangular and quad-dominant meshes. Derivatives are computed analytically through a computational graph, and mesh-quality and inversion diagnostics report the validity of each deformed mesh. It implements the mesh deformation research described in [1] and is in early development.
