Vensim 10.4 is now available. Causal tracing has been upgraded along with a new interactive document tool. Lots of other small tweaks and performance enhancements. More details available at vensim.com/documentation/… And you can download directly from vensim.com/download/

@r99247873 It's really best to use the official forum.

@Vensim This is my diagrama with a flor going from population to deadths. And in the equation editor only apear two variables : population and births. I think the equation should be something as: Population + Births-Deadths

@Vensim I have problema with my PLE+. When building the model for population growth (rabbits) in the display for Population, the equation should be: Births-Deaths, but the variables that apear in causes are: Population and Births. How can I correct the error? Tks.

A great use of both Vensim and sdeverywhere. The BRIDGE simulation quantifies the impact of NIH budget cuts in the US. linkedin.com/posts/msjalali… You can try the simulator yourself at mj-lab.mgh.harvard.edu/nih-budget-sim…

A big congratulations to our good friends at Climate Interactive (including two of our own staff) on winning the 2025 System Dynamics Applications Award. climateinteractive.org/blog/en-roads-…

We hope all those that attended the conference got home safely. Looking forward to Delft next year already.

We are delighted to present some of the recipients of our sponsorship at the System Dynamics conference.

This is just one of the interesting posters at the SD conference this evening.

We are delighted to be here in Boston for the System Dynamics conference. Feel free to pop by and say hello if you are here. We're always pleased to see and talk to you.

@topeseun294 Do you mean a table function? vensim.com/documentation/…

@Vensim How can I create a function for my model? How do I know which exact variable that needs function or equation

We've released Vensim 10.3 Featuring a new equation editor, Bayesian inference, data files when publishing to the web, MCMC algorithm updates, plus lots more. More details at vensim.com/documentation/… And you can download from vensim.com/download/

Dicari manusia yang jago vensim cepattttttt😭

@Lucy_Worsley I think your Facebook page has been hacked.

@_s_h_hosseini @systemdynamics_ @UOW Done. I had to cut a few characters here and there to fit within the X limits, but the message is still all there. Good luck. Get in touch if we can help in any way.

@Vensim @systemdynamics_ @UOW Yes, please.

Next week, I will hold a mini-workshop on #SystemDynamics with @Vensim, co-hosted by the Oceania chapter of the @systemdynamics_ Society and @UOW Centre for Supply Chain Research (CSCR). Date & time: June 20 – 1:00-4:30 pm. Register now: uow.au1.qualtrics.com/jfe/form/SV_dm…

@rajeee1000 We are not familiar with Mathcad so cannot comment. If you can provide an example for us to look at, then yes, we would consider.

@Vensim Does Vensim include the complete capabilities of the very similar equations only tools like Mathcad? If not, it should in the future versions.

@cowdealer I'd urge your professor to upgrade to the latest version. If they have a different layout, they are using a version we no longer support (and haven't done for years). Most of the tools are identical, it's just different icons.

@Vensim Ok now i feel bad but thank you for the reply- I have my tutor helping me out already. Just a bit annoyed that my professor is using an older version with a different layout

I hereby publicly denounce you @Vensim
