5.3 BOUNDARY RECOVERY FOR 3D DT
5.3.1 Introduction
Taking the triangular surface mesh as input,
boundary recovery
requests all triangles on
the input surface mesh be preserved without introducing Steiner points on the boundary.
The integrity of the boundary (both geometry and topology) is crucial in meshing by com-
ponents, parallel MG, partial re-meshing, multi-interface problems, etc. With the develop-
ment of the FEM and its applications, how to generate a tetrahedral mesh with an integral
