Transient Thermal: nonlinear heat equation
I am trying to study heat transfer in a material whose properties depend on temperature ( thermal conductivity and heat capacity depend on temperature - i.e., nonlinear heat equation). And I use Thermal Transient module in the Workbench.
I have specified the temperature dependences of thermal conductivity and heat capacity through the "Engineering Data" interface. But unfortunately,
I have found that one can specify only 100 points for each temperature dependence. I.e., I can assign the values of thermal conductivity to only 100 values of temperature!
Could someone propose me another way of introducing temperature dependent thermal conductivity (may be its possible to code a function and to link it somehow to Transient Thermal ?? - I can not figure out how to make this).
Thank you in advance!:)
