Converging process
 

hi everyone
which one is more important in converging process? residuals or stability of residuals?
for example our continuity residual is considered 10e-6, after some iterations , the residual reaches to 10e-6. Is this residual enough for stopping process or we have to continue iterations to reach stability?

residuals monitor the change between sucessive iterations. when the residual is very small it means your solution is not changing, its a mathematical convergence but to deterime if you have obtained a correct physical solution you need to look at more information.
