free surface boundary conditions
 

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 ,

Re: free surface boundary conditions
 

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
