we write k_steel in h in the boundaries for Shrink Fitting of an Assembly tutorial

Hello,
How can h(heat transfer coefficient) and k(thermal conductivity) be same in ? we write k_steel in h in the boundaries for Shrink Fitting of an Assembly tutorial.

This is a tutorial example showing how to set up and solve a transient heat transfer problem with multiple subdomains. The heat transfer coefficient "h" typically depends on many factors such as the interface or boundary type, surrounding material or fluid, and fluid flow regime. In your own model you would typically estimate "h" from measurements and experiments or use a fitted expression such as for example can be found in the references below.
