Inconsistent results ....

Hi Friends,

I was doing an analysis of an impeller, diffuser setup. I had given some boundary conditions and solved and obtained a result.

For the same geometry I didnot change the boundary condition and rerun the analysis this time I got totally different result from that of the previous one.

Why is flow simulation 2010 giving inconsistent results. Any possible clues/ help ???
