Hi, I want to do some postprocessing of an already solved simulation.
Under solution I added an apdl code which also uses the command "set" and it works for the first run.
As soon as I execute the APDL code a second time I get the error "An error occurred while attempting to open the results file file.rst.  ".The rst file is rather big 140 GB.

Just the APDL code:

set,1

creates the error.

I use WB2023R2 Static Structural Simulation

Hi,

Please see if the following forum thread helps: Error occurred when the post processor attempted to load a specific result file (ansys.com)

Hi,

unfortunately this doesn't help. The APDL works all the time after a fresh Workbench restart.
Just if I execute the post apdl command a second time it doesn't work.

Hi,

What if you try the following via GUI or command:

/POST1  
INRES,ALL   
FILE,'file','rst','D:/

The post apdl command is executed within Workbench not in classic. In classic evwerthing works fine.

I have found with commands objects that they sometimes work when they are executed immediately after the solution, but when you try to run them a 2nd time without rerunning the solution they don't.  Sometimes it's necessary to issue a resume command at the top of the commands object (which would require a database to be saved in Analysis Settings> Data Management>).  In the APDL gui when you issue the SET command without resuming a database the program asks if you want to recreate the database from the nodes and elements on the rst file.  Perhaps that doesn't work in batch mode.
