Conjugate Parallel Issue!
 

Hello. I'm not too familiar with conjugate simulations in Fluent, but I created my mesh and set up my contact interfaces and boundary conditions in serial mode. Was able to run without issue but need to be able to open in parallel. I saved the .cas and .dat files, and when I try to reopen with more than 1 processor, I get a cortex exception. It appears to be an issue with the interfaces and maybe partitioning them, but Fluent recognizes these contact interfaces automatically when the mesh is loaded so I don't know how to get around this problem? If I try to start from scratch and load in the .msh file in parallel mode, it fails when the adjacent interfaces are being read.

Interfaces
 

Fluent does not require interfaces for fluid-solid communication. You can use standard, conformal mesh. Fluent will automatically create wall-shadow pairs.
