QMESH,RENUM,QPLOT. Self-Organizing Mesh Generation
- Sandia National Laboratories, Albuquerque, NM (United States)
A set of five programs which make up a self-organizing mesh generation package. QMESH generates meshes having quadrilateral elements on arbitrarily shaped two-dimensional (planar or axisymmetric) bodies. It is designed for use with two-dimensional finite element analysis applications. A flexible hierarchal input scheme is used to describe bodies to QMESH as collections of regions. A mesh for each region is developed independently, with the final assembly and bandwidth minimization performed by the independent program, RENUM or RENUM8. RENUM is applied when four-node elements are desired. Eight-node elements (with mid-size nodes) may be obtained with RENUM8. QPLOT and QPLOT8 are plot programs for meshes generated by the QMESH/RENUM and QMESH/RENUM8 program pairs, respectively. QPLOT and QPLOT8 automatically section the mesh into appropriately-sized sections for legible display of node and element numbers. An overall plot showing the position of the selected plot areas is produced.

- Other Information: DN: The mesh plotted by QMESH does not include any mid-side nodes, and RENUM8 input cannot refer to any mid-side nodes. mid-side nodes appear only in QPLOT8 plots. The CRAY1 version uses the SNLA-environment Graphics Compatibility Systen (GCS) library to generate graphics output. Suitable alternatives are required for graphics output in other environments. Calls to the plotting package can be eliminated if no P character is included in the scheme input.; PBD: 1 Nov 1991
