blown up power flow code

Hello Everyone,

Let's say I use ierr = psspy.fnsl() to run power flow and the power flow does not converge or blows up. How can I distinguish between these cases? ierr returns 0 for a converged or a blown up case.

Any help is appreciated.

Thank you very much.

Use API solved to check the result of the last solution attempt. I.e.:

ival = psspy.solved()

As a detail: Blown up generally means solved returns value of 2, 1 might be still ok, 0 is completely fine.
