Hello,

Aside from simulation-time can "extreme" under-relaxation have an impact on the accuracy of the solution?

Regards

Yes, an extreme under-relaxation has an effect on the solution. If you under-relax too much, you risk to have false convergence, which brings to "false" solutions.

Hi

ap

Ok thx.

If you have the time, could you plz recommend any paper och text book that covers false convergence?

Regards

Sorry, I don't know a paper which talk about the problem of "false convergence". It has been presented to me during a course I attended to.

However, a book which covers under-relaxation techniques should be of help.
