Victor, thank you. Removing Ngl.end() solved the trouble.

Hi Matt,



It looks like Ngl.end() is destroying the workspace. Try removing that and see if it works.

Dear PyNGL users:



The following set of errors I am receiving are hard to diagnose. Any assistance would be appreciated. My script is attached and errors are below. I've a created a small script to plot COAMPS model output. The script works for one iteration, but then gives a series of errors on the second iteration. However, if I skip the first iteration, the second works... and so one. .



Thank you,

Matt
