Hi guys,

I an running a simulation on a tank filling. Previously the solution converged but as I re-initialised the problem (for checking), the solution did not converge anymore. Fluent still performs its calculations but the residuals are way too high!!

If that has happened to anyone, could you tell me why and what I can do to resolve this?

Cheers

I have never heard of this happening. It has been my experience that running the same simulation twice will produce exactly the same results.

Were you're simulations run with the same bc's/solver/methods/initialization/etc?

I do not know then. I am not a FLUENT expert, I have only been using it for about a year now.
