Abstract Improvements to a local modification-based
anisotropic mesh adaptation procedure are presented.
The first improvement focuses on control of the local
operations that modify the mesh to satisfy the given
anisotropic mesh metric field. The second is the parall-
elization of the mesh modification procedures to support
effective parallel adaptive analysis. The resulting proce-
dures are demonstrated on general curved 3D domains
where the anisotropic mesh size field is defined by either
an analytic expression or by an adaptive correction
indicator as part of a flow solution process.
1 Introduction
Unstructured mesh adaptation has proven its efficiency
for improving the accuracy of numerical solutions used
