I want to solve a heat transfer problem, where the thermal conductivity changes with temperature. How should I achieve this?. I can’t find a similar example in examples.
Hi @tao-zhan18
We don’t have any specific examples of this, but we have many that involve heat transfer. I would suggest getting your system working with a constant heat conductivity. You can then look into replacing these constants with sympy variables and have separate nodes that can then calculate the thermal conductivity based on the temperature for you.
Different PDE, but an example of using a predicted variable for a material property can be found in the inverse problem example with a model that predicts the fluid viscosity.
