Thank you very much, Tom! I didn't have the payoff report on, and I accidentally found out about the cin fp error files. But I didn't get any error when I used the .cin input to simply run the model, which was surprising. I can run the calibration with the payoff report on to see what else is being ...

When I estimate the parameters of a model using over-dispersed Poisson (attached), the optimizer generates 'fp_err_ctx' .cin files. But when I run the model with these inputs, I don't get any fp errors. I might be missing something, so could you please help me understand what's happening? Thank you!...

Thanks a lot, Tom. Yes, I'm doing sensitivity after MCMC, and all I had to do was to include NOISE SEED as a variable in the model and set MY_SEED = 0, which goes into the Random functions. Such a nice feature! Thanks a lot!

Is it possible to manually add this option in the .vsc file as a text? (to avoid the hassle when using cmd/dll)

Hi Tom, thank you for your quick response. I'll email you now.

I can see the .out files being generated when running a cmd file manually. But when I use the same command "MENU>RUN_OPTIMIZE|o" combined with venpy/dll on windows, it generates the .vdfx files but not the .out ones. Is there a way to save the optimized parameters? On a related note, I wan...

I have another question. Is it possible to tell 'SIMULATE>ADDCIN' command to read the .out file from a subdirectory rather than the parent directory where the model and .cmd files are saved? If so, could you please provide an example? Thanks again!

I could run it. Thank you so much!!

Hi. What is the equivalent of this action in the command script? FYI, I want to run MCMC with the values obtained from Powell. Thanks so much in advance!

Thank you, Tom! I think I got confused thinking all chains start from the same point and MCINIT controls the level of "added noise" for sampling. But noise is clearly controlled by other parameters, so not sure why I got confused. Thanks a lot for the clarification!

I couldn't find the explicit definition in the tutorial, so I'm posting my question here: When running a standalone MCMC with multiple chains per each parameter, do all chains start from the same starting point?

Such a great graphical visualization for simultaneous equations! Very cool feature!

Yes, they also show up in the equations.

I'm not sure how it would look like on other machines, but on macOS, you can use emojis instead of regular characters.

Thank you so much! 10.3.0 works perfectly now! Lot's of great features!

And it now appears in the default resolution. I guess for the very first time it was outside of the display area (all displays). it's all set now. Thank you!

When the equation editor was open (and it was not showing up), I changed the resolution and it suddenly appeared!

Of course, I had done that. I only had two monitors connected and was suspecting the extra displays are acting up. They did not. Just a FYI, I have a 14-inch Mac. I can restart it to see what happens. Is it possible that some interface settings from the previous version in the shared folder are inte...

Equation editor seems to get activated but nothing shows up

It now throws an error on 10.3.0. I agree with you. it might be the difference between ARM & Intel. Now that I installed 10.3.0, Mac throws an error (which is what we expect). But I have a VM on Mac (Windows 11 using Parallel Desktop). The VM still has the same problem (not throwing an FP error)...

Thank you, Tom. I found another workaround a few minutes ago, but I'll keep Inkscape in mind. For what it's worth, here's the workaround: I had a hidden variable, and when I dragged it outside of the area of the current variables, I think it somehow expanded the printable area. Thanks again for the ...

Hello, could you please help me properly export the svg of the attached model so that all variables appear in the final product?
Here are some of failed attempts:

Did you see that I don’t get the error?

The original test I did was on M3, macOS 15.3.1, and Vensim 10.2.2. I just tested it on an M4 machine (but still on macOS 15.3.1) and Vensim 10.1.3. It doesn't throw an FP error either. So, I'm not suspecting Vensim or the build version anymore. Which macOS are you using? At any rate, do you have an...

macOS sequoia 15.3.1 Please see this: https://youtu.be/qywCbmphC5I Note that the first test is on my MacBook Pro M3, macOS 15.3.1, but the second one is on a windows machine (Intel) using Remote Desktop. FYI, Parallels Desktop (on macOS), doesn't throw FP either, so it could be related to ARM or App...
