Regarding source term
 

Dear Friends,

I use Fluent 6.3 version, earlier I used starcd for fuel cell simulation. Recently I am developing Fluent UDF for fuel cell simulation. In starcd, if I want to fix a scalar value then I can use
S1P=GREAT*SCI
S2P=GREAT
Source = S1P-S2P*SCALAR(IS)
where SCI can be a constant or an arbitrary function of the parameters. Do we have similar function (like 'GREAT' in starcd) in fluent?

Thanks in advance,
