iterations in der log-file (FEM / Genormte Berechnungen/OpenFOAM)

Guten Morgen,

mir ist aufgefallen, dass in all meinen log-files, das Phänomen auftritt, dass ich den p_rgh mehrmals vorfinde. Vor allem mehrmals mit "no of iterations 0"
In den tutorials scheint das nicht zu sein.
Ich frage mich ob und was für ein Fehler das ist.

Anbei mal ein Auszug von einer log-file:
