Question

Hi all,

I am sure that I am missing an obvious solution here but it is eluding me. Is there a way to end a simulating using a post processor?

For example I want to end a simulation if the minimum element quality is too low. I have a post proc that outputs min quality, but I can't find a way to have that value interact with the executioner.

Thanks!

Hello

Yes, this capability just got added to MOOSE. You ll need to install the "next" branch, because it has not been released to the main branch yet.
You ll want to specify a PostprcoessorConvergence and specify nonlinear_convergence_name to the name of that object in the Executioner

Great, thanks!

Actually, does this method then override the normal convergence parameters?
I want to keep non linear tolerances, but just kill the simulation when a certain mesh quality is reached.

ok just use this instead with PPs on the quality

this CV object method will eventually do what you want but not yet. We dont have a "Combo" convergence to specify more than 1 criterion

Ah this is exactly what I was looking for! Thanks!
