PVSyst unexpectedly closes during long batch runs

[Andrés Fernández]

Hi

When I run large batches (many simulations) PVSyst runs for a few hours then suddenly closes without an error dialog.

I’ve tried smaller batches without problems and monitoring Task Manager but can’t find a clear cause (like memory spikes).

Any suggestions on logs to collect, known bugs, or settings to stabilize long batch runs? 

PVSyst Version: 8.0.14. OS: Windows 11 (full updated). RAM: 16 GB.

Thanks in advance
