BUG Vensim 8.1.0 crash nearly every model check

Post by skuk »

Just upgraded to 8.1.0, but the problem was occurring with the last version as well. Vensim quits with no error message when checking a model (cntl-t) or entering Synthesim, sometime in the "checking equations" process. The model is not trivial (attached) but not enormous. It seems to be able to withstand a check or a run immediately after opening, but if I edit an equation, save, and check again Vensim crashes most times.

It's the massive lookup tables you have in the model. The info they contain should really be in a data file.

The annual ones are probably fine; the ones with a step of .25 year are likely the problem.

Obviously this should not cause a crash, but it's not immediately clear whether the fix will support the largest tables.

Are you on Mac or Windows? I think I've got a fix for this (but it needs a little testing).

If you email us with your licence details, I'll give you access to the test version.
