A complementary code of the article
Stefan Krömer, Jan Valdman - Surface penalization of self-interpenetration in linear and nonlinear elasticity
Description: a 3D linear elasticity is formulated as an energy minimization and combined with the (nonlocal) self-interpenetration term defined on the deforming domain boundary
The code is based on modification of benchmark 4 from the article
1) A. Moskovka1 and J. Valdman - Fast MATLAB evaluation of nonlinear energies using FEM in 2D and 3D: Nodal elements
Vectorization/Solver of linear elasticity is taken from the article
2) T. Rahman, J. Valdman - Fast MATLAB assembly of FEM matrices in 2D and 3D: nodal elements
Mesh visualizations are taken from the article
