How does DualSPHysics handle the free surface?

Could someone explain it to me, even if shortly and point me in the right direction for ressources?

I know boundaries are using DBC or mDBC, but I actually do not know what is done at free surfaces. In multi-phase simulation I suppose it is handled as a phase interface or something like that.

Kind regards


  • The reason I find it difficult to understand what actually happens, is that the more I read about it, the only thing I find is that at the free surface, one just applies kernel correction and then everything is ok? Atleast for a mono-phase simulation

    Seems kind of easy compared to FVM where you have to use Volume of Fluid methods etc., so I just would like to be sure I actually understand it.

    Kind regards
