Velocity profile in boundary condition

Recommended Posts

Hello,

 

I would like to know if it is possible to define a velocity profile as a boundary condition in AcuSolve (using either Hypermesh in the AcuSolve user profile or AcuConsole).

 

Basically I need to define a boundary layer at my inlet, and would like to control its shape as I please.

 

Thanks in advance!

 

Best regards,

Ricardo

1.  If you use inflow type average velocity, mass flux, or flow rate a profile at the inlet is generated as part of the solve process.

2.  If you would like to specifically define an inlet profile, you'll need to use Nodal Boundary Condition on the inlet surface for the desired velocity component(s) with type user function.  You would then define the desired profile in the user function.  If the profile can be defined as a function of a single quantity, you may also be able to make the NBC of type linear.
