Hello
My colleague and I are having some problem running an immersion cooling simulation. I defined a new material to define material property based off a documentation of novec 7500. However once I run the simulation it gives the above error. The attached is the file.
Thank you

Hello Brian,
In the Settings window corresponding to the "Material 1" node of the Model Builder, you can see 3 stop sign icons located next to the three properties you tried to define. This is to signal that data is missing. Add "Cp(T)", "rho(T)" and "mu(T)" in the "Value" column of that table and you will have told the software to use those functions with those arguments for those properties.
Best,
Jeff

Cp is the customary variable name for heat capacity. See also a screenshot, from your file, which I have attached. FYI, it looks like you may have forgotten to define the density and dynamic viscosity too. Added: Looks like Jeff Hiller answered first. :-)
