Mesh for calculating heat transfer in solid/fluid

Hi,

I want to calculate the heat transfer from a fluid to a solid.
I have found a good mesh for the fluid region. But I can't find a good mesh for the solid region. Using the Courant number to find a good mesh also results in a bad calculation (see extention).
You can see a cut through the mesh.

Does someone have an idea?!
Maybe it is better to use the extrude option to generate the volume mesh?

I think I have to use a finer mesh in the solid region than in the fluid region. However I get bad results...

Mesh size:
solid: 5*10^-4m
fluid: 3*10^-3m

Best Regards,
