Hi all,

I've just started using OpenFoam, having previously used Fluent. In Fluent there was a really useful option to include a loss-coefficient based fixed pressure boundary condition, although I can't remember what it was called! It worked as setting a pressure at the boundary:

p = p0 + k 1/2 rho v^2

The user set p0 and k, and then rho and v were taken from the solution at the boundary. This became essential in modelling flows with multiple channels/paths.

Has this been implemented in OpenFoam? If so, what's it called?

Thanks for your help,
