Hello,

I am using createpde to create a transient heat transfer model. The thermal properties of my product is a function of temperature but is not a linear function, and I wrote another function with temperature as the input to calculate the thermal properties. I found a linear function is usually written like this k = @(~,state) 0.3+0.003*state.u, how to write it for a non-linear function with temperature as the independent variable?

Thank you very much!

Best regards, Shengyue Shan

在 MATLAB Online 中打开

In those models, state.u is the temperature, so go ahead and use any appropriate anonymous function, such as

@(location,state) 0.052*exp(3.6-state.u)
