Postprocessing


Postprocessing Command Blocks

At v14 postprocessing command blocks can be added and evaluated after At v14 postprocessing command blocks can be added and evaluated after the solution is complete (no complete re-solve is required).

When a post solution command block is evaluated Mechanical will write a batch solution file and submit it to the ANSYS solverbatch solution file and submit it to the ANSYS solver.

— The default name for batch input file is “post.dat” — A corresponding output file “post.out” is also generated in the folder.

Use the RMB on the Solution item to open the solution folder to view the Use the RMB on the Solution item to open the solution folder to view the files.

Tips for Postprocessing

1 Not all quantities are written to the result file by default1. Not all quantities are written to the result file by default. — If you plan to postprocess force or contact data you will need to set the

output controls prior to the solution (Analysis Settings > Output Controls). — This can also be set as the default using the Tools > Options > MechanicalThis can also be set as the default using the Tools > Options > Mechanical

> Analysis Settings and Solution.

76www.caeai.com

Tips for Postprocessing Command Blocks

2 Named Selections of geometry are converted to nodal or element2. Named Selections of geometry are converted to nodal or element components in the ANSYS database (active memory during the solution).

— The generated components are NOT written to the result file and will NOT be found if requested in a post-solution command block.found if requested in a post solution command block.

— To get around this save the MAPDL database prior to the solution: • Analysis Settings > Analysis Data Management and set “Save MAPDL

Database”.• This can also be set as the default using the Tools > Options > Mechanical >

Analysis Settings and Solution. • Add a “resume” command at the top of the postprocessing command block.

77www.caeai.com


3 Use the SET command to read all quantities from the results file3. Use the SET command to read all quantities from the results file. — The MAPDL database is saved after the solution but not all quantities are

stored.

4 When evaluating a postprocessing command block on a model with a4. When evaluating a postprocessing command block on a model with a completed solution you may need to redirect ANSYS to the appropriate result file type.

— The solver uses the default /POST1 > FILE setting which looks for a file with— The solver uses the default /POST1 > FILE setting which looks for a file with an .RST extension.

— If the analysis is of another type you will need to use the FILE command in the command block.
