Hi

I am getting high residuals and the solution doesn't converge after 100 intinerations...

Do you have idea of what can cause this problem. After one simulation using simpleFoam and kwsst the only which doesn't converge is p file...........

Please see my screen shot in attachment.


Thanks

Try reducing the underrelaxation factor for the pressure and perform (much) more iterations
