TraceFEM for the membrane problem using distance functions on and tetrahedra
Mirza Cenanovic
We consider Trace finite element methods for the linear membrane problem on second order tetrahedral elements. To accomplish this, zero-level set reconstruction methods for second…

Finite element procedures for computing normals and mean curvature on triangulated surfaces and their use for mesh refinement
Mirza Cenanovic, Peter Hansbo, Mats G. Larson
In this paper we consider finite element approaches to computing the mean curvature vector and normal at the vertices of piecewise linear triangulated surfaces. In particular, we a…
