Hi I am trying to use APDL Commands to automate some postprocessing in Ansys Mehcanical and I am recieving the following warnings: 

*** WARNING ***                         CP =       0.219   TIME= 12:58:41
 Invalid coordinate system= 101.                                        

 OPENED FILE= file.txt FOR COMMAND FILE DATA
  COMMAND FILE CLOSED

 *** WARNING ***                         CP =       0.219   TIME= 12:58:41
 The item label NAME is not recognized by the NSEL command.        

 

  The NSEL command is ignored.

 

 

 

This is the part of my code where I set the named selection and local coordinate system I would like to use:

 

! Define the single named selection
NamedSelection = 'Fold1 RZ' 
CoordSystem = 101

CSYS, CoordSystem  ! Set the coordinate system

*CFOPEN, FilePath + 'Debug.txt', txt
*VWRITE, 'Coordinate System: ', CoordSystem
(A, F8.0)

*VWRITE, 'Named Selection: ', NamedSelection
(A, F8.0)

*CFCLSE

! Apply the Named Selection (ensure the selection is active)
NSEL, S, NAME, NamedSelection

Here is an image of the coordinate system:

 

And here is the named slection:

Any assistance you could provide would be greatly apperciated!

Hi

See this and the help manual (command ref. section in mapdl help):

20 APDL Commands Every ANSYS Mechanical User Should Know – PADT

For instance to choose named selection issue:

CMSEL,S,Fold1RZ

All the best
