User-Defined Conductivity Model

Hi experts,

I want to use Conductivity_Model for my work and use a user-defined cubic spline curve fitting for conductivity of a material. I found the following but could not find one for conductivity in acuSolve tutorial. Does anyone know how to do it?

Thanks.

When you create your new Material, rather than specifying the Thermal Conductivity to be Constant, you can set it to be Cubic Spline, then define the data table for your known points. You can make the conductivity a function of temperature, etc, as the Curve Fit Variable.

I have one more question. If I want to use USER FUNCTION for conductivity_model and add C file, how can I do it?

I found this one:

https://2022.help.altair.com/2022/hwcfdsolvers/acusolve/topics/acusolve/conductivity_model_acusolve_com_ref.htm

It says to modify the input file. Can it be done from within the GUI (like momentum_source user function) and later compile using acuMakeLib instead of modifying the input file ?

The HyperWorks CFD GUI does not yet support type = user function. You would need to use the Export icon from the Launch AcuSolve panel, then edit the .inp to set the type to user function and add the appropriate parameters - following the example on that page you mentioned from the Command Reference Manual.
