ANSYS UDF Source terms has a variable called "eqn" being passed that denotes the Equation number. Is it possible to find the value of eqn for each equation that we solve?
DEFINE_SOURCE (cell_t c, Thread *t, dS, eqn) { }

I know for sure that:
IF eqn=EQ_X_MOM -> X momentum equation IF eqn=EQ_Y_MOM -> Y momentum equation IF eqn=EQ_Z_MOM -> Z momentum equation But I can't remember where I found it out, so I don't know about the other equations |

Ok, I found it. There is an enum in the file mem.h
For latest Fluent versions the file should be in fluent/fluentxx.y.z/src/storage Within your ansys installation folder. Just search it for, say, EQ_X_MOM and you will find the others |
