Opening BC losses
 
Hi,

I'd like to know if there is a way to ask CFX to use the total speed instead of the normal speed to compute the losses when using the "opening" boundary condition.

Mathematically, it's quite simple: just use f \left( 1+\left( \frac{U_{t}}{U_{n}} \right) ^{2} \right) instead of f for the loss coefficient.

If there's no built-in solution, is it possible to use a function for the loss coefficient?

Thanks.
