Loosely Coupled CHT and Shell Conduction Compatibility

      Hello!

      I'm trying to perform a transient CHT calculation in Fluent. The model has Shell Conduction. When I click "Run calculation" I get an error:

      "Error: get-thread: invalid thread id (integer) or name (symbol)

      Error Object: #f".

      In the manual, neither one nor the other functionality has an indication of incompatibility with each other. What is the problem? Separately from each other, they do not cause an error.

      Hello Can you try a case without shell conduction and see if you are getting the same error?

      You're inattentive. I wrote "Separately from each other, they do not cause an error".

      And you're rude. Where is the shell conduction wall relative to the solid zone? Images may help.

      Ok. There are 3 shell conduction walls. One is between solid and fluid zones, one is between two fluid zones and one is on external boundary of fluid zones. But I tried to deactivate them, leaving only one at a time. Same error. Only if I deactivate all of them there is no error.

      The mesh is 3d and conformal?
