The simulation runs without crashing now, but the subhourly clipping loss seems very high. This is for the default Detailed PV / No Financial model with the weather file attached below:

Weather file used for testing:

38.13_-86.34_psm3-tmy_60_tmy_no_dni.zip

Which Irradiance data option did you use for these results? I'm having trouble replicating results.

I'm not seeing those results now. Perhaps I was in the wrong version of SAM. Please ignore my previous comment.

However, I am getting an exception in cmod_pvsamv1.cpp when I run a simulation with the default DNI+DHI option with the weather file that has no DNI data. The release version of SAM 2023.12.17 correctly generates an SSC error message, so I think this may have been introduced in this branch:

Paul, I caught that error too, apologies for not updating. I am working on a fix and will push shortly.

That will fix NatLabRockies/SAM#1685
