Abstract
Geometric criteria. based on geometric feature analysis, are presented in this paper to deal with the evaluation of finite element surface meshes. Theoretical aspects as well as numerical examples are provided in the context of finite element methods. The proposed measures can be used to govern surface mesh modification algorithms and are useful to validate the surface meshes within a general mesh adaption scheme for which the size map is provided via an a posteriori error estimate.
