An anisotropic unstructured triangular adaptive mesh algorithm based on error and error gradient information

Marcuzzi, F.; Cecchi, M. Morandi; Venturin, M. - In: Mathematics and Computers in Simulation (MATCOM) 78 (2008) 5, pp. 645-652

In this paper, an algorithm based on unstructured triangular meshes using standard refinement patterns for anisotropic adaptive meshes is presented. It consists of three main actions: anisotropic refinement, solution-weighted smoothing and patch unrefinement. Moreover, a hierarchical mesh...
