Error estimates for a multidimensional meshfree Galerkin method with diffuse derivatives and stabilization [PDF]

Ingeniería y Ciencia, 2013
A meshfree method with diffuse derivatives and a penalty stabilization is developed. An error analysis for the approximation of the solution of a general elliptic differential equation, in several dimensions, with Neumann boundary conditions is provided ...

Numerical comparison of three a posteriori error estimators for nonconforming finite element method

Moroccan Journal of Pure and Applied Analysis, 2023
In this paper, we propose to compare three a posteriori error estimators namely equilibrated, star-based and residual based for the Poisson problem and the Stokes problem with lowest-order Crouzeix-Raviart finite element discretization.
