Hello Rojeeb.
How many scenarios are You running? It looks from your screenshot that You don't have regions in Your model, so I expect You would run many scenarios.
I had this problem often in the past and it was due to 1 thing: Big model.
You are using 32-bit LEAP, which (like all 32-bit programs) have a limitation on RAM use of 2GB. If You are running a big model, this may be enough, and generally make LEAP start acting strange.
I would encourage You to:
- Check if Your computer is running 64-bit Windows (guide here: https://support.microsoft.com/en-us/help/827218/how-to-determine-whether-a-computer-is-running-a-32-bit-version-or-64)
- If so, download the 64-bit version of LEAP (same license, same features) (link here: https://www.energycommunity.org/default.asp?action=download)
- Try Your model again.
Does this help?
