I have created the mesh for my room and radiator and the mecshcheck shows no errors. For the simulation a radiator is attached to the wall however heat only seems to be emitting from the surface against the wall and is not transferring into the room. I have set up the heat transfer coeffiecent of the room and the radiator is set to a tempertature. Neither the room or radiator increase in heat. Any suggestions to why this may be?

How did you set the radiator temperature? What other boundary conditions are there? A cut plane of the mesh may be diagnostic.

I set the radiator as a temperature of 294K, the room walls were set to a free stream value of 287. There is no wall thicknesses applied to any walls. An warning has appeared when switching to solution: 

Following expected zones were not found in the current mesh:

 radiator:119

 shelf:116

 Found Following new zones in the current mesh:

radiator:116

 shelf:119

Model Information is incompatible with incoming mesh.

Found some missing and new zones in the mesh. To make mesh compatible with settings, please visit "Match Zone Names" panel

(File->Recorded Mesh Operations->Edit Incoming Zones... -> Match Zone Names...).

What exactly did you set as 294K? Radiator wall, cell zone, internal wall etc.

Just the Radiator wall

OK, and a cutplane view of the mesh? I assume you've got wall & wall:shadow pairs around the radiator? Please post the image I asked for.
