boundary condition
I am modeling the water pipe leakage jetting towards wall with surrounding sand.

!) where the outlet should i define? The water pipe leakage hole? or the wall?? As i'm facing the problem of the water flow internal within the leakage hole. ---It is supposedly flow towards the sand then towards the wall, not internal glow.

2) I would like to study on erosion of wall. So how can i define the primary phase (water) flow with the sand hitting the wall??
