FEM2D_MESH_DISPLAY is a MATLAB program which plots the nodes and elements of a finite element mesh.
FEM2D_MESH_DISPLAY reads the FEM model of a mesh, that is, a file listing the node coordinates and a file listing the indices of the nodes that form each polygonal element. It displays the mesh, with optional number of nodes or elements.
fem2d_mesh_display ( 'prefix', node_vis, element_vis )where 'prefix' is the common prefix for the node and element files:
