Hi Steve,

I saw this post and hope you can help me to solve this error.

I am going to run system coupling in HPC cluster. I followed the Ansys tutorial for oscillating plate model step by step and exported all of the files we need.The only problem i faced was when i was going to add Data transfer 1 and 2. I got this error and i do not what is this error for?

AddDataTransfer(Interface = "Interface-1",

                    TargetSide = "One",

                    SideOneVariable = "force",

                    SideTwoVariable = "FORC"

                    )... ... ... ... 

Traceback (most recent call last):

  File "CommandConsole", line 4, in

  File "PyLib/kernel/commands/", line 74, in func

  File "PyLib/kernel/commands/", line 28, in executeCommand

  File "PyLib/kernel/commands/", line 121, in executeCommand

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

  File "PyLib/cosimulation/datamodelinterfaces/", line 176, in addDataTransfer

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

As i now in fluent setup, we define deforming and system coupling faces under dynamic meshing part. 

I will appreciate if you or anybody could help me to solve this error.
