Chapter 7:The General Postprocessor (POST1)
• You can use the element table as a "worksheet" to do calculations among results data. This feature is
described in Additional POST1 Postprocessing (p. 170).
• To save the element table, issue SAVE,Fname,Ext in POST1 or issue /EXIT,ALL when exiting the ANSYS
program. (If you are using the GUI, follow the prompts in the dialog boxes that appear when you choose
Utility Menu> File> Save as or Utility Menu> File> Exit.) This saves the table along with the rest of
the database onto the database file.
• To erase the entire element table from memory, issue ETABLE,ERASE (Main Menu> General Postproc>
Element Table> Erase Table). (Or issue ETABLE,Lab,ERASE to erase just the Lab column of the element
table). The element table will automatically be erased from memory if you issue a RESET command
(Main Menu> General Postproc> Reset).
7.1.4. Special Considerations for Principal Stresses
Principal stresses for SHELL61 elements are not readily available for review in POST1. By default, the principal
stresses are available for all line elements except in either of the following cases:
• You have requested an interpolated time point or angle specification on the SET command.
• You have performed load case operations.
In the above cases (including all cases for SHELL61), you must choose Main Menu> General Postproc>
Load Case> Line Elem Stress or issue the command LCOPER,LPRIN in order to calculate the principal
stresses. Then you may access this data through ETABLE, or any appropriate printing or plotting command.
7.1.5. Reading in FLOTRAN Results
To read results data from the FLOTRAN "residual" file into the database, issue the FLREAD command (Main
Menu> General Postproc> Read Results> FLOTRAN 2.1A). FLOTRAN results (Jobname.RFL) are read
with the normal postprocessing functions or commands, such as SET (Utility Menu> List> Results> Load
Step Summary).
7.1.6. Resetting the Database
The RESET command (Main Menu> General Postproc> Reset), allows you to re-initialize the POST1 command
defaults portion of the database without leaving POST1. The command has the same effect as leaving and
re-entering the ANSYS program.
7.2. Reviewing Results in POST1
Once the desired results data are stored in the database, you can review them through graphics displays
and tabular listings. In addition, you can map the results data onto a path (for details, see Mapping Results
onto a Path (p. 155)).
7.2.1. Displaying Results Graphically
Graphics displays are perhaps the most effective way to review results. You can display the following types
of graphics in POST1:
• Contour displays
• Deformed shape displays
• Vector displays
