Is it a bug of Flunet?
 

Dear all, I have compiled a UDF for the inlet velocity. After compiling it and setting it as inlet boundary condition, the Fluent can get exact inlet flow waveform I prefer. However, if I want to decrease the inlet velocity to 50% of the previous one and change the corresponding factors in the UDF before compiling and recalculating, The Fluent still get the same flow rate as the previous one. The inlet velocity does not decrease 50% as I expected.

So is it the bug of FLUENT? (I thought my UDF shall not be wrong for I only change the resultant velocity to multiply 0.5)

I do need your help! Thanks a lot!

hi may,

Try to read again your case after compiling.

good luck.
