p_rgh is plottet far ahead of the simulation, why?

Hey guys!

I am plotting my residulas for my simulation with chtMultiRegion (air flows around a geometry in a wind tunnel) and I noticed that the pressure is always far ahead of the other values. I attached a snapshot of my simulation that i run for 1000 iterations, but p_rgh is shown until 2000.
Why does that happen, is there something wrong?

Hi Clau,

is it possible that you just plot iterations and not time and that you do more p_rgh iterations per timestep as iterations of the other values?

regrads,
Teresa

Ah, yes you are right!

Then it is related to my other post: p_rgh diverges and is calculated multiple times?
