Looking for UDF that inlet velocity of fluid ranges along the 3D rectangular channel
 

hi guys,

I'm working on a 3D mini-channel and the Reynolds number range from 200 to 800, where the corresponding inlet velocity of the fluid medium range from 0.1 to 0.38 m/s.

anyone could help me with the udf ? cause im new to fluent and i have no idea how to write it...

I will appreciate your help,
best regards.
