I am running a two way FSI with Transient Thermal and Fluent for coupled thermal analysis.

The geometry is simple: a thick SiC wall with one side attached to a pipe which runs superheated steam. The other side of the wall receives high temp radiation.

I've set up both TT and Fluent. Everytime I run the system coupling solution, it just abort automatically with the error messages down:

System coupling run completed with errors. System Coupling Service reported: System coupling run aborted by user or due to fatal error: A solver failure occurred during the run in the Transient Thermal system Please do not save the project if you would like to recover to the last saved state.

Anyone has any idea what caused the error?
