viscosity defined by pressure and temperature

i want to define the viscosity as a function of pressure and temperature.
I need that to calculate an ol, that is mixed with CO2.
I just have a table, where i can go from pressure and temperature to the mix ratio and then from mix ratio and temperature to the viscosity.
Is it possible to give fluent that Table?
Do I need to programm that with UFD?
And: Maybe someone did that before and send me the UFD?
Thanks a lot!

Yes, it is possible to use such a table in Fluent.
Yes, you have to use a UDF for that.
No, I don't have such a UDF ready, and I doubt if somebody will have exactly what you want.
Make some efforts in writing such a UDF, and if you come into specific problems, you can ask here.
