On optimal convergence rate of finite element solutions of boundary value problems on adaptive anisotropic meshes

Agouzal, Abdellatif; Lipnikov, Konstantin; Vassilevski, … - In: Mathematics and Computers in Simulation (MATCOM) 81 (2011) 10, pp. 1949-1961

We describe a new method for generating meshes that minimize the gradient of a discretization error. The key element of this method is construction of a tensor metric from edge-based error estimates. In our papers [1–4] we applied this metric for generating meshes that minimize the gradient of...
