The FEPLOT program is an interactive, three-dimensional graphical environment for use with the output files created by the FEGEN, PDIST and PTEMP analysis programs. The FEPLOT program is capable of generating plots of the finite element model which is generated by the FEGEN computer program. In addition, the FEPLOT program is capable of generating color contour plots and deformed shape plots from the output files that are generated by the PDIST and PTEMP Analysis programs. In addition, hard copy output is obtainable from an HP-Paintjet or an HP-Laserjet printer.
This section describes the allowable command lines and the arguments associated with them. The command lines are entered in free-field format (i.e., entries are separated by one or more blank spaces). Required arguments which are not entered on a command line are individually requested by the program. In addition to entering commands from the text-window, a mouse driven pop-up menu is available for use with all of the commands that are available in the FEPLOT program.
A list of the twenty-five allowable command lines is given in Table 9-1 on page 9-2 of this manual. This table contains a brief description and page number for each command line.
