Erosion Problem

ahbao86 · November 22, 2011, 05:45

Hello all,

I am new in CFD STAR-CCM.
I would like to do some erosion simulation in STAR-CCM.
I did the tutorial to get erosion rate.
But after I import my model and model, i couldn't get my erosion rate as in tutorial. there might be several problems i discovered is happened but i cannot solve.

1. It has reversed flow on face outlet.
2. It has negative pressure at the corner.
3. Do I set correctly for the boundary condition?? because the required area is wall.
4. I couldn't get erosion rate although i get the pressure distribution with reserved flow.

Anyone could help me solving this problem, I will very very appreciate your helping.

Thanks a lot~~

Regards,
Ah Bao
