Hi,
I am writing a UDF in order to implement a vaporization/flash-boiling law for DPM-Calculations.

Now I have the following problem:
I have a droplet surface at boiling Temperature T_b, and the gas phase is at temperature T_g. In the calculations for the evaporaton mass flow from droplet to gasflow I need specific heat, thermal conductivity and viscosity of the gasphase, but at reference temperature calculated as

T_ref=2/3*T_b+1/3*T_g.

In the UDF-manual it is described I can access the specific heat with C_CP(c,t) but this would give me the specific heat of the cell, meaning at T_g.

How can I access the material property library, depending on material and temperature, is this possible?

Thanks for your help!

Thanks, I have now defined my properties as UDFs and therefore can access them inmy UDF of interest.
