Hello engineers,

a time ago posted a thread concerning solid phase anisotropic thermal conductivity. I found the way how to do that but I had to use command line. But now I need to do parametric calculation and I don't know how to define this conductivity without using command line. I tried to define it as an expression but I am not sure if I am doing well.

I defined the function for each coordinate axis but I don't know if it is OK and I also don't know how to implement these functions into expression.

I just don't know how to put all three "subfunctions" into one (expression that defines anisotropis thermal conductivity).

Please does anyone have any idea?

Thank you for all advices.
