All particles falling out of domain
Using designSPHysics to construct my cases with stl files as both the solid objects and the initial fluid portion I am unable to keep any of the particles in my domain.
My main use case is as an artificial wave tank, in which I can place breakwaters. however when i start the simulation all the fluid falls due to gravity then leaves the faces of the boundary.
I am coming over from packages like openFOAM, where I would define the simulation boundary conditions, but I cant see a way to do this.
