"PIMPLE: not converged within 4 iterations" and slow progress

Using SimScale Fluid Flow / CFD

My project was estimated to take 140-180 minutes, yet it’s now at 1% with 50minutes already gone. To that point i went to see the solver log ;

And i have a lot of Pimple iterations 1; 2; 3 and under the fourth i read the message:
“PIMPLE: not converged within 4 iterations”

Which got me quite curious to what that means, as there was no reference to settings related to that?
My project:

If anyone would want to take a look and verify (settings should be quite coherent) in case you think this was a man made mistake

Hey again,

As stated in the other post, I would like to know why are you using a transient model, when a Steady-State one should be enough in this case.

If you really need a transient model, then you should ramp up the velocity from zero to max values to help the solver ease into convergence.
