67. Dr. Mohammed Al-Hazmi FEM67 Units The ANSYS program does not assume a system of units for your analysis. Except in magnetic field analyses, you can use any system of units so long as you make sure that you use that system for all the data you enter. (Units must be consistent for all input data.) Using the /UNITS command, you can set a marker in the ANSYS database indicating the system of units that you are using. This command does not convert data from one system of units to another; it simply serves as a record for subsequent reviews of the analysis.

68. Dr. Mohammed Al-Hazmi FEM68 Undo Main Menu>Preprocessor>Session Editor The UNDO command brings up the session editor, a text window that displays all of the program operations since the last SAVE or RESUME command. You can modify command parameters, delete whole sections of text and even save a portion of the command string to a separate file. The file is named jobname000.cmds, with each subsequent save operation incrementing the filename by one digit.

69. Dr. Mohammed Al-Hazmi FEM69 Hints Tips on SAVE and RESUME:  Periodically save the database as you progress through an analysis. ANSYS does NOT do automatic saves.  You should definitely SAVE the database before attempting an unfamiliar operation (such as a Boolean or meshing) or an operation that may cause major changes (such as a delete). o RESUME can then be used as an “undo” if you don’t like the results of that operation.  SAVE is also recommended before doing a solve.

70. Dr. Mohammed Al-Hazmi FEM70 File Management Tips Run each analysis project in a separate working directory. Use different jobnames to differentiate various analysis runs. You should keep the following files after any ANSYS analysis:  log file (.log), database file (.db), results files, load step files, if any (.s01,.s02,...), physics files (.ph1,.ph2,...). Use /DELETE or Utility Menu > File > ANSYS File Options to automatically delete files no longer needed by ANSYS during that session. Hints
