hello,
is it possible to define a non uniform velocity profile as a boundary condition at a velocity inlet; that is, can i set the velocity profile at the inlet to be parabolic, for example, instead of constant? if yes, how? thank you |

It is very easy. Please read the UDF manual file, you will know how to do. I remember that there is a example like what you want to do.

Hi!
There is another way: write the profile as a table (x,y,vx,vz,vy or something like that) or take it from another simulation (with write profile). Than, import the profile (file->read->profile) and use the vel. components as vel. components in the velocity inlet BC. You may orientate the profile, look in the fluent manual, how that works.
