free surface boundary conditions

December 3, 2002, 04:27

Hi, I have a problem with the free surface in Star: I try to simulated the flow around a ship, so in the inlet I have light (air) and heavy (water) together with the same velocity. The point is: how I define the inlet?I have to define the inlet for the vof scalar too?

Someone has a simple macro to send me?

Ciao ,

Two inlet boundaries that meet at the surface, one with scalar conc 1.0 the other with scalar conc 0.

or

Use bcdefi.f, with an

if (zc.gt.surfacelevel) then scalar(1)=0.0 else scalar(1)=1.0 endif
