Hello!
I have a question concerning the velocity profile. I did the UDF function and compiled it in ANSYS fluent, however I need to assign it to a BC of inlet velocity? if so, it only gives positive values of the velocity... how can the velocity change from + to - on a boundary and thus change the direction of the velocity vectors? should I change the type of boundary conditions? Thank You !! |

if we speak about inlet boundary condition ->
positive velocity means flow inside domain negative velocity means flow onside domain through inlet best regards |

hello everybody, I need a UDF for the set velocity component.
for example. I want to set y velocity or anything else. so how can write it? for example on the fluent, you can set ... how can write it on the UDF, now? |
