Composite wall heat conduction
 

Hi,
I am modeling heat conduction through several different materials in a cylinder (heating probe with coil, powder core, steel wall). I am using sliding mesh approach and I define interfaces between different regions.
While for 2D problems it is not to much work, in 3D it is just painstaking, I need to create every single interface manually, and then when I do a small change in the geometry, I repeat all that.
Is anyone aware any other approach for this than the Sliding mesh approach?
Thanks!
