Vensim DSS Crashes on macOS

Post by aliakhavan89 »

Hi,

I figured that during the final steps of the optimization (specifically, using Powell with Random starts), Vensim crashes without saving the optimization reports. I am on Vensim DSS 8.0.9 and running macOS version 10.15.4.

In the crash report generated by the operating system, I found these that might be useful:

I also checked the exact model with the same optimization settings and it works well.

I think this might be a bug in the payoff reporting that we've fixed in development already. If so, the .out file written should still contain your final parameters, so you can rerun the endpoint solution.

The .out file provides the endpoint solution, but the ***_sensitive.tab is empty. I am using Powell to estimate the confidence intervals.

If you can upload or send us the files that cause the crash, we can take a look into it.

Also make sure that "Payoff report" is unticked when doing optimization.

I sent the model via email with the instructions to the steps that cause the software crash.
