Good morning everybody,

I need help with a simpleFoam case, any start follows a interuption with time step continuity errors (log file below)
and I have no idea why I got this error???!!!!
My checkMesh are Ok, and any changes on nNonOrthogonalCorrectors factors an relactionFactors are pointless (nNonOrthogonalCorrectors from 0 up to 5 andt the relaxationFactors (pressur) 0.5 down to 0.1 (for the other 0.7-0.5)).

But nothing change any the same error, but on a other iteration step .

A last word to the controlDict dt=1/startTime 0/endTime 1000 .
Hope of any advice, Thx
