I made a lot of intermediate calculations which took up a huge amount of disk space. Since I did not need them, I deleted these calculations. I ran the database optimisation but this did not recover any space. How can I reduce the model to a sensible size before I take the project forward?
There is a neat possible solution but you can’t export a complete scenario tree.You can export a single scenario using
file>export archive. Select NoiseMap archive (.nma)
- This will export the plant, activities, geography, receivers (but not the results) for a single scenario, but this might be enough.
- Then start a new model and ‘import archive’. This will recreate the scenario but without the dross.
- Don’t forget to commit changes, preferably to a new scenario.
- I tried this with your test model and it drops to about one-tenth of the size.
- Of course, I haven’t checked whether there is important information missing, other than the scenario tree.
But at first glance it seems fine. And it’s very quick to do.
