salzferkel · August 1, 2011, 18:06

Hi i using Fluent 6.3 in Windows with Visual 2008.

it runs . only one thing i missing is, i usually using "printf" in my udf to give out some values so i can evaluate during the simulation.

my problem, during the simulation fluent 6.3 didn't showing me the values of "printf " as my demanded.
it shows only the usuall x-y-z velocity k-eps ect...

on ansys 12 my udf works without problem.

anyone can help ?

Hi
I have the same problem, did you solve it?, for me its working in 3D but it doesn't work in 2D and printf doesn't print anything.
