SPH Modeling PROBLEM

Hello Everybody,

 

I am currently trying to model correctly SPH Method with Radioss on a cylinder of 5mm Radius and 20 mm Length. At 10mm which is half the length of Cylinder i made a Membrane of 2 mm Radius Whole. So, basically i want to model correctly SPH Particles of Water which are halfly filled at one side of cylinder  and will pass through the membrane to the Other end of the Cylinder. I have model the Contact between Fluid and the Wall of Cylinder by Type-7 Contact with GapMin settings. 

 

So can anybody help me in this Model to correctly Model the Pressure and Velocity of SPH Particles through Inlet and Outlet Boundary Conditions ? Can anyone also help me out in SPH Property setting values like Mp (mass of particle) , Smoothing Length, quadratic Bulk Viscosity and Linear Bulk Viscosity and so on..... I also wanted to know how to model the contact properly because Contact Pressure is very high in My simulation results. 

 

Thanks !

 

Regards,
