Function with parameters

I'm trying to simulate a multicomponent gas flow.
The gas has more than 20 different components, each one with different properties.
The heat capacity of each component follows the following law:
Cp(a,b,c,d,e,T) = a*T +b*(T^2)+c*(T^-1) +d*(e)
Where a,b,c,d and e are parameters which differ from component to component and T is the gas temperature.
I'd like to know if there's a way within CFX for me to write this function Cp(a,b,c,d,e,T) and call it within the materials properties.
This way, when I'm setting each components properties I don't need to write the whole expression, just call the Cp(a,b,c,d,e,T) with the appropriate parameters a,b,c,d and e.
thanks a lot

You cannot do CEL functions like this. You can write a fortran subroutine to do it. But I would just write it all out in CEL. Using a text editor it should not be too hard to knock up the CEL expressions for each of the 20 components.
I realise this is not "elegant" and a computer scientist would choke on his weeties, but it should work, is straightforward and will get the job done.
