Boundary conditions help~

January 17, 2007, 05:18

Hi,

I am working on a project involving fluid flow simulations through a tuning fork-shaped tube - 1 velocity inlet, 2 pressure outlets.

Am having problems defining b.c. I am able to obtain inlet boundary conditions, in terms of pressure profile and velocity(have created an udf), but I am not sure what to use for both outlets conditions.

Does anyone have any ideas?

Many thanks in advance!

Use pressure outlet boundary with gage pressure 0. This is the mostly used one in general.
