derivative of source term
 

Hi,
i would like to learn about ds[eqn]
my source is= C_YI_G*C_U
what is the ds[eqn]=?
thanks

Just come across this problem myself and found a useful section in the FLUENT UDF manual. If you have the UDF manual it's section 4.3.17 (note it's in the FLUENT UDF manual not just the FLUENT Users Guide). I think the UDF manual should be in the following folder under Fluent.Inc if the folder structure is the same on your computer as mine;

Fluent.Inc\fluent6.3.26\help\pdf\udf

If not then private message me and I will email it to you.
