Dear OF users,

I have a problem about the time step continuity error when I use the solver rhoSimpleFoam to simulate a steady state nozzle.

The time step continuity errors for me is relative bigger:
sum local=0.164391 global=-0.00639303 cumulative=-16.4307

What does this time step continuity error actually mean and how can I reduce them?

Thanks a lot!

I think this is out of memory of variable type which defined in C++ code. You can change type of variable.
But, actually, your problem may be carried out incorrectly. So you can check this firstly.

Hi Dang,
thanks a lot for your help.
But what do you mean by changing type of variable and how can I realize this.
thanks!
