laplace-beltrami-eigensolver

This software computes the eigendecomposition of the Laplace-Beltrami operator on the charts of a Riemannian manifold. It uses finite elements via the FEniCS computing platform (version 2019.1.0) as well as the eigenvalue solvers in the SLEPc library. The user can specify an arbitrary metric tensor by writing its entries as valid C expressions.
