Hi,

Does anyone know how add gravity as a source in the momentum equation using UDF?

I would appreciate if you can answer the question.

Thanks, Suresh

Hi,

DEFINE_SOURCE is suitable for your problem and the dimension is N/m3.

Or, If you want to set ordinary gravity vector, set the "operating density" and "gravity vector" in the panel of "Define-Operating conditions".

Thank you

FJ
