Abstract :
A high quality unstructured triangular mesh scheme for adaptive finite element methods (AFEM) is presented. The algorithm is based on Superconvergent Cluster Recovery (SCR), and coupled with remeshing procedure and centroidal Voronoi tessellation (CVT) optimization techniques. The advantage for SCR is robust and easy to implementation. Normalized edge lengths which based on a metric are employed as the remeshing criterion. A high quality mesh can be obtained by CVT. Numerical test shows that the scheme can be applied successfully to a typical elliptic equation problem and other relevant steady-state problems in engineering.
