Hello,

  when openning the Mechanical Modeller, we run into the above error message and it fails to start.

 

platform:  CentOS 7.9.2,   AnsysFLST version 22.2            command to start:  runwb2

 

Steps to produce the error:  Open Workbench ==> Make a stead-state thermal project ==> double click on geometry ==>

Make a simple geometry in design modeler (e.g. a simple cube), then in Workbench double click on Model.

 

(Any other workflow that result in opening the Mechanical modeler would result in the error)

 

# After selecting Steady State Thermal and double clicking on Geometry, a little error window pops up:
WB Error while loading the DocingPane.

Then the "Steady-State Thermal - DesignModeler window shows up.

 

The following are the exception trace shown on the terminal. If you need more information, please let me know.
