Hi Steve,


I am trying to run system coupling in Hpc cluster. I followed step by step the ansys tutorial for oscillating plate model and exported the files we need. i did not face any problem until when i was going to add Data transfer 1 and 2 in system coupling. i got this error.


AddDataTransfer(Interface = "Interface-1",


                    TargetSide = "Two",


                    SideOneVariable = "force",


                    SideTwoVariable = "FORC"


                    )... ... ... ... 


Traceback (most recent call last):


  File "CommandConsole", line 4, in


  File "PyLib/kernel/commands/CommandDefinition.py", line 74, in func


  File "PyLib/kernel/commands/__init__.py", line 28, in executeCommand


  File "PyLib/kernel/commands/CommandManager.py", line 121, in executeCommand


  File "PyLib/cosimulation/externalinterface/core/dataModelInterfaces.py", line 157, in execute


  File "PyLib/cosimulation/datamodelinterfaces/__init__.py", line 176, in addDataTransfer


RuntimeError: Invalid variable provided for side one. Variable does not exist: force.


 


As i know we define deforming and system coupling faces in the fluent setup under dynamic meshing part and i did it. but about defining the force and displacement  variable we define them in system coupling not in fluent.


i will appreciate if you or anybody else could help me to solve this problem.
