How to speed up a large model

[ajclarke]

I have a model that uses subscripts. Some variables have 3 or 4 dimensions, and that seems fine in the test data I've put through. However there are 850,000 subscript elements overall and I only need to plot results from 150 of those elements as the others are for the calculations along the way.

Is there a way of doing the following:
1) Getting Vensim to only save in the VDF file the nominated elements and not the rest
2) Getting only the final values exported for the others rather than the whole time history

Thanks...

I think what you want is a savelist, to restrict the .vdf to the 150 or so variables you're interested in.
