Default coupled boundary condition
Posts: n/a
hello all, I am trying to solve a simple conjugate heat transfer problem. now i want to assign coupled boundary condition to my solid wall so that it can couple energy and momentum equations at that point. i figured one way to do it was to assign interior boundary condition at faces and change it in fluent to wall and then select coupled. but that somehow is not working. fluent is giving me error that says" Cannot change ---- to interior because there is only one adjacent cell thread". Can somebody tell me what the error is about and how do i assign coupled boundary condition to solid surfaces for conjugate problems.

Thanks in advance for reply Nikhil

you cannot do this. You have to couple fluent with abaqus.

Hi Nikhil,

Are you planning to make solid and fluid interface boundary? U can try assign no boundary condition to the surface, because fluent solver will do it for u when you export your mesh.

U can refer to my post at "How to solve 2 different specify continuum types" at

Good luck!
