Working on this three issues arise:

Usage of PAUSE over the gRPC interface

Interestingly, it seems that the PAUSE command does not work on gRPC mode.

>> mapdl.run("pause")

 PAUSE is not a recognized BEGIN command, abbreviation, or macro.  This  
 command will be ignored.

Ignore these messages by setting 'ignore_errors'=True

However, it does work in a normal context:

I believe I'm using it wrong.... Pinging @mikerife @FredAns @koubaa

Usage of PAUSE on Student version

Additionally, it seems the command PAUSE does not work well in MAPDL student version (or maybe I'm using it wrong).

But if you start an MAPDL instance, and then issue PAUSE:

$ ansys -dir /tmp
...
...
 RUN SETUP PROCEDURE FROM FILE= /ansys_inc/v241/ansys/apdl/start.ans

 /INPUT FILE= /ansys_inc/v241/ansys/apdl/start.ans  LINE=       0

 BEGIN:
pause

 *** WARNING ***                         CP =       0.518   TIME= 16:14:02
 This application is now PAUSED, making its license available for use by 
 another application in this Workbench session.  All commands to this    
 application will be ignored until an UNPAUSE command is typed in the    
 Command Window of this application and successfully processed.          

 BEGIN:

and then start another MAPDL instance, you get a Maximum licensed number of demo users already reached error but it starts.

License error showing on the student version

Also it seems that launching student version shows the Maximum licensed number of demo users already reached. error before starting successfully:

 ANSYS LICENSE MANAGER ERROR:
 Maximum licensed number of demo users already reached.

 ANSYS LICENSE MANAGER ERROR:
 No such feature exists.
 Feature:       mech_2

I have made sure there are no more Ansys processes running using ps aux | grep ansys.

@germa89 you are not using pause wrong; at least that is what I think. It is pretty strongly implied in the help that it is for mapdl interactive. You can enter other APDL commands while paused but the UI throws an warning for all (except the unpause). My guess is that this is built into the UI and not MAPDL per se....if that makes sense.

germa89 commented 3 weeks ago

Wrapping PAUSE on a non_interactive context (which uses input) does not help to avoid the error message shown above.

 *** WARNING ***                         CP =       3.962   TIME= 11:51:49
 PAUSE is not a recognized PREP7 command, abbreviation, or macro.        

Ignore these messages by setting 'ignore_errors'=True.
