Attached is the UDF - I have combined two UDF's from the tutorial regarding giving an inlet velocity profile and a source term in the X-momentum eqn. Separately they are working fine but when I combine them by interpreting, this the error:

Error
chip-exec: combined: wrong return type:
float udf function expectedchip-exec: combined: argument 1:
incorrect type (38): int expectedchip-exec: combined:
argument 2: incorrect type (5): pointer expectedchip-exec: combined:
argument 3: incorrect type (0): pointer expectedchip-exec: combined:
argument 4: incorrect type (0): int expected

Also I have a fundamental doubt:
In a UDF like this where I have inlet velocity variable and also a source term, I will hook the UDF in Inlet velocity and Sources ; the same UDF is attached to inlet velocity and momentum eqn ; but how does FLUENT distinguish between the application of these two? What if it confuses between the condition?

I hope I have made my point clear. I am a beginner and learning about UDF


Thanks,
Yash

I got the solution after scouting around earlier threads.
