Hi every body,

In Star-ccm+ i have a problem for my DFBI simulation of high speed planing craft (2DOF with and without overset mesh) and that is air ventilation under the hull.

For this i had already tried mesh refinement and the time step to resolve the issue but the problem is still there.

I read in several articles that negative source (Sink) should be used to solve this problem.

Can any one help me that how to use negative source's?

Thanks in advance!
