fem2d_mesh_display


fem2d_mesh_display, a MATLAB code which plots the nodes and elements of a mesh involved in the finite element method (FEM).

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.

Usage:

fem2d_mesh_display ( 'prefix', node_vis, element_vis )
where 'prefix' is the common prefix for the node and element files: and node_vis is an integer defining the node visibility: and element_vis is an integer defining the element visibility:
