Research direction

Start by tracing the solving process and how model references are held before and after the solver runs. Check how an optional NetCDF write and reassignment could fit without changing the model result; done means the option reduces peak memory while preserving solving behavior.

Written by the indexing model from the issue text.

Description

enhancement performance

We could optionally write the model references to a NetCDF file just before the solving process and reassign afterwards. This could reduce the total memory usage by 30%. (Example: for a 112 GB peak memory example solving, 31 GB was held by linopy and 81 GB by gurobi.)
