Hello all,

I am trying to write an analytic function to define thermal conductivity of a domain. The thermal conductivity in this case depends on both density as well as temperature. I have defined density with an interpolation function based on data, which varies with depth, and titled this profile "density". I am unsure how use density in my analytic function of conductivity ?

as a simple case, say I want to write an analytic function titled "k" as: density*T

If I define the arguments as T, density - I get the right surface plot but a little off on values. It doesn't let me write: density(y)*T. Any insight is appreciated!

Thanks!
