quad_mesh_rcm, a FORTRAN90 code which computes the Reverse Cuthill McKee (RCM) reordering for nodes in a mesh of 4-node quadrilaterals.
The user supplies a node file and an element file, containing the coordinates of the nodes, and the indices of the nodes that make up each element.
The program reads the data, computes the adjacency information, carries out the RCM algorithm to get the permutation, applies the permutation to the nodes and elements, and writes out new node and element files that correspond to the RCM permutation.

quad_mesh_rcm is available in a C++ version and a FORTRAN version and a MATLAB version.
MESH_BANDWIDTH, a FORTRAN90 code which returns the geometric bandwidth associated with a mesh of elements of any order and in a space of arbitrary dimension.
QUAD_MESH, a FORTRAN90 code which handles meshes of quadrilaterals over a 2D region;
RCM, a FORTRAN90 code which carries out reverse Cuthill-McKee computations.
TET_MESH_RCM, a FORTRAN90 code which applies the reverse Cuthill-McKee reordering to a tetrahedral mesh of nodes in 3D.
TRIANGULATION_RCM, a FORTRAN90 code which reads files describing a triangulation of nodes in 2D, and applies the RCM algorithm to produce a renumbering of the triangulation with a reduced bandwidth.
