Regions not converged
Hello,
I am performing a chtMultiRegionSimple foam case and i get the note: "Regions not converged after 20000 iterations."
The solution has become stagnant and the residual quite low, still it shows the note at the end.
The result looks to have reached saturation at T=3788, from then it gives same values till 20000th iteration. Please find the excerpts from the log file.
Kindly help!!
