Temperature dependent material properties
 
Hi,

I am new to CFX and want to enter temperature dependent material properties for density, viscosity, specific heat, thermal conductivity and electrical conductivity.

I know that this can be done in Fluent using UDFs but can't find how to do this in CFX.

My temperature dependent properties have a number of reference temperatures so the polynomial function isn't really an option.

Can anyone help?

Thanks

Have a look at the tutorials for setting up new materials. You can specify variable properties with CEL expressions (eg polynomials) or interpolation between points, or a user fortran routine.
