Hi all,

I can't find how to properly set up basic heat transfer from a fluid to a solid. Here's what I've done so far:

In Gambit:
- create 2 adjacent faces
- connect the 2 adjacent edges into only 1
- specify continuum types to solid face and fluid face
- specify boundary conditions, the merged edge between solid and fluid is specified as wall

In Fluent:
- Fluent automatically created wall and wall-shadow for the fluid-solid boundary and the thermal boundary condition is set to coupled.
- No error messages, check case, everything seems ok.

Looked at attached jpg, the cold solid never heats up, instead, it lowers the temperature of the fluid along the fluid-solid boundary.

Quick help or redirection towards a tutorial that I don't know the existence of would be very appreciated. Thanks.
