unchanged residuals and changing results
 
hi all,

In a case I am doing, all the residuals are below 1e-5 and keeps unchanged for a very long time. However, all the results like temperature contour or surface coverage profile keeps changing. Is it normal?

As far as I am concerned, if all the residuals are constant, then all the results should keep unchanged though they might not be converged results, right?

can somebody give some help?

Best.

weiqiang.

Residuals can be unchanging even when results change because residuals are averaged over the domain.

If the results are unchanged then that would be convergence...
