ACCOPTION causes pymapdl run to fail about pymapdl HOT 7 CLOSED

@germa89 most laptops don't have a GPU that would be automatically used - have you set the following environment variable?
ANSGPU_OVERRIDE=1

@mcMunich check the file0.err file and see if it shows that the CUDA driver needs to be updated. Mike

this is going to be a bit tricky. Delaying to the next week (I need my Windows laptop)

from pymapdl.

I got the following error:

 *** ERROR ***                           CP =       0.641   TIME= 15:59:19
 The GPU accelerator capability cannot be activated with the ACCOPTION   
 command.  Please read the following message for more details.           

 *** ERROR ***                           CP =       0.641   TIME= 15:59:19
 The capability GPU was either not ordered with this Ansys installation  
 or the appropriate product was not selected for this session.           
  Contact your Ansys support person for more information.

So it seems that to use ACCOPTION you need to also do something like:

mapdl = launch_mapdl(additional_switches="-acc NVIDIA")

Notes

To inject env vars in MAPDL process:

mapdl = launch_mapdl(additional_switches="-acc NVIDIA", add_env_vars={"ANSGPU_OVERRIDE": "1"})

I acknowledge PyMAPDL should return something more explicit than Connection terminated.

PyMAPDL needs a better error catching... either at launching or during runtime.

I'm closing this issue because there is no PyMAPDL issue per se.
