Default Parallel solver, divergence

Hi all,

I'm having a problem when using the parallel solver where the solution stops and it says divergence detected.

The issue is that when running the EXACT same set of iterations on the serial solver, no divergence occurs and the solution converges very well. Also when divergence is detected, the residuals indicate that the solution is converging normally. For the parallel computation I'm using 4 processors.

Does anyone have any ideas? Any help is very much appreciated.

Thanks Phil
