dyntools.CHNF() causes python to crash. Help!

I am running a python script to do dynamic contingency analysis. The command dyntools.CHNF() (to get the output channel values) causes python to crash when there are some NaN values. There is no error message, python just crashes.

Has anyone else encountered this behavior and found any ways to either skip over this issue or fix it? Ideally, i want to skip to the next simulation when this happens.

I couldnt find the command 'dyntools.CHNF()' in the PSSE API module as well. I was looking for ways to skip getting the output data if there were NaN values in the output channels.

Test to use try statement in order to avoid Python crash.

For documentation:

import dyntools
help(dyntools)

tried that already. since python crashes, this doesn't work. checked the dyntools help. There is nothing helpful in the options for dyntools.CHNF. To fix this crash, i need to know if the output channels contain any NaN characters, before running the command: dyntools.CHNF().

I assume PSS/E will crash if you open the corrupt out-file inside PSS/E.
