Hello everybody!
Tried to search this problem but still cant find the answer.
The problem is when i set up through command editor orthotrpic properties as follows:
THERMAL CONDUCTIVITY :
Option = Orthotropic Cartesian Components
Thermal Conductivity X Component = 60 [W m^-1 K^-1]
Thermal Conductivity Y Component = 60 [W m^-1 K^-1]
Thermal Conductivity Z Component = 0.3 [W m^-1 K^-1]
END.
as the result, i get very impressive temperature raises around near the solid solid interfaces like they dont work at all. I heard it can work if i set up 1:1 mesh connection in these interfaces, but i only have one GGI option in cfx-pre. How to deal with this?
Thanks in advance!

I understand orthotropic thermal conductivity is a beta feature only, so you should be aware of strange results when using this model.

So if you have heard that it works with 1:1 mesh connections then you should try that. You will probably have to remesh to do this.

thanks for your reply, but the next question out of this is how can i remesh these faces for 1:1 connection (ansys mesher), when match control tool is only available for faces of one body?

I would do this using multibody parts to enforce a 1:1 mesh.

Try the geometry and meshing forum for a more complete answer.
