SPH method - in-canal flow
Hello,
I am trying to model the flow in the canal with the SPH method. The canal has the shape of a rectangular prism. I determined the surface where the flow will start by creating a csurf. SPH particles are produced in line with the normals of the elements on this surface. I aim for a continuous and dense flow of particles.
- I think that if I make the mesh on the yellow marked surface more fine, the particles will become denser. I also observed this. However, all particles were not formed at the same time. Why could this be?
- How can I make the particles in the x direction more dense? ( Is using finer mesh the only solution to this? )
- Particles are occurring far apart from each other in the y direction. The particles are forming as in Figure 1. So I don't observe continuous flow. How do I ensure continuous particle formation?
I would be glad if you help.
Thank you.

Hello again,
I wanted to explain the situation I mentioned on a simple model.
As seen in Figure 2, as the mesh size of the inlet surface decreases, the particles become more dense in the y direction. But the particle gap has increased in the x direction.

Thank you.
