Vectorized 3D mesh refinement and implementation of primal hybrid FEM in MATLAB

Harish Nagula Mallesham, Sharat Gaddam, Jan Valdman +1

In this article, we introduce a Face-to-Tetrahedron connectivity in MATLAB together with a vectorized 3D uniform mesh refinement technique. We introduce a MATLAB vectorized assembl…

A priori error analysis of the -mortar FEM for parabolic problems

Sanjib Kumar Acharya, Ajit Patel, Talal Rahman

In this article we derive a priori error estimates for the -version of the mortar finite element method for parabolic initial-boundary value problems. Both semidiscrete and ful…

Convergence results with natural norms: Stabilized Lagrange multiplier method for elliptic interface problems

Sanjib Kumar Acharya, Ajit Patel

A stabilized Lagrange multiplier method for second order elliptic interface problems is presented in the framework of mortar method. The requirement of LBB (Ladyzhenskaya-Babuška-B…
