All particles falling out of domain
Hello,
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.

You always have to open Case_All.vtk in Paraview to see what particles you have created. I am pretty sure that some walls are missing.
In any case if you know the dimensions of your tank is better if you created that as a box with the faces you need instead of loading STL.
Other option for you is to start using our DualSPHysics package directly...

Hello,
Simulation boundaries are open in DSPH, so you need to define/draw the tank (either use the gencase tools or import a geometry ".stl")
