FEM2D_PACK
2D Finite Element Routines


FEM2D_PACK is a MATLAB library which contains utilities for implementing the finite element method.

The emphasis is on simplicity and clarity. Only the 2D case is handled, with a choice of low order triangular and quadrilateral elements.

A few routines are included for computing a "sphere grid", that is, a finite element mesh on the surface of a sphere.
