SLIC: An Interactive, Graphic Mesh Generator for Finite-Element and Finite-Difference Application Programs

摘要

SLIC was designed to automate the mesh generation procedure by relieving the engineer of much of the computational effort. Only a few key points (to describe the model geometry adequately) need be input with discrete coordinates. Elements are constructed after their corresponding nodes have been generated and verified. Improvements over earlier codes include the following: interactive or batch input or a combination, interactive error recovery, compressed data storage, stacking of input commands, selection of analysis code input file structures, interactive HELP package, alphabetic keyword input options, free-form input, error-corrected condensed RERUN command file, interactive NEWS package, and interactive real-time graphics display with option of creating a file for hard copy. This manual includes the following sections: introduction, conventions used in this manual, running SLIC, important comments and SLIC facts, handling errors, fundamental commands, 1-D generation commands, 2-D generation commands, 3-D generation commands, node numbering commands, sliding interfaces, information commands, control commands, display commands, special commands (boundary conditions, mesh enhancement, miscellaneous), and user subroutines. Appendixes containing a sample SLIC session, a sample user subroutine, command syntax, and an error summary are also provided. 17 figures. (ERA citation 05:005220)
