 February 14, 2007, 10:51 Boundary Profiles #1 smillerhh Guest   Posts: n/a I am using measured profiles for the velocity vector boundary conditions on a mass flow inlet. When I do a countour plot of the velocity components in the boundary face I do not exactly see the profiles that I specified, but something that is already smoothed out. It looks to me as if FLUENT does not show the specified bc information, but somehow extracts the data from the adjacent cells. How can I do a contour plot of my bc as I specified them and how FLUENT - hopefully - applies them?

Hope this helps.

In Fluent u can give either velocity bc or mass flow bc,..but not both on the same inlet, so, what i guess is u were first giving velocity bc & then giving mass flow condition on the same inlet, so what fluent is doing is taking the mass bc, & thats why u r not getting the same velocity profile as u defined first. so check for the above thing.
