Ventana software support forum

Update: I have not observed any comparable behaviour with 9.2.4.

Firstly - thank you all for your patience in answering all of my questions. Secondly - I've searched the forum and documentation and couldn't find an answer to this: is there a way to save and reload multiple sets of parameter settings? Use case: I want to develop a set of edge cases. Let's say in t...

Agree that individual warnings would be overkill. A small pop-up that makes a user aware that warnings exist might be a decent compromise.

Thanks for considering!

Yes, that looks to be the issue. The warnings appear with a regular run of the model. Is there a way to adjust the suppression settings such that the warnings appear during SyntheSim?

Thanks

Note: this is an issue because the model outputs non-sensical results without warning. This makes it more difficult to debug.

Hi all, I've set minimum boundaries on several conditions, yet when they are realised, there is no warning given. I have checked "Preferences" and validated that warnings are not suppressed. Image shown as an example where the minimum was zero, and the actual was -1. No warning window is w...

The step-by-step is literally the same as described above, except instead of clicking on the "formula" widget, I click on the "trash" widget. When I then click on the variable, it crashes.

I'm happy to share a video if that's helpful.

I've also now observed that the application crashes when deleting shadow variables as well.

Hi Team,

I've taken a short video of the behaviour occurring repeatedly in succession. Would you like me to upload/send it somewhere?

Thanks

Thanks Tom! Honestly I had forgot about your blog as a resource .. I found it last semester but hadn't come back to it .. I'll check it out! On another note, is there any reason that I shouldn't implement a closed-loop as shown below? Conceptually, the idea of the flow "stopping" when peop...

nvm, realised I can just copy/paste: [vensim] ModelsOld0=/Users/maxxsilver/Documents/School/2021 Sem 2/CapStone/Submission Pack/Saved Research/Covid SIR Model/community corona 8.1.mdl ModelsOld1=/Users/maxxsilver/Documents/School/2022_Sem_1/Capstone/PrEP Model_v9.7.mdl ModelsOld2=/Users/maxxsilver/D...

Sure. I've tried to upload but I'm receiving an invalid filetype error. Is there an email address you'd like me to send it to?

Thanks - this was helpful. I'm still not fully across the distinction between discreet and continuous delays, but I think that may be for another day. I take your point that Delay Fixed is probably not the correct choice here. From what I can tell, I should consider implementing Delay1 or Delay1I. I...

Not sure if using the old or new GUI - how might I tell? I believe it's the new. --- 1. Add shadow variable (Time Step) to model 2. Add connection arrow from shadow variable to auxiliary variable 3. Save 4. Open formula of auxiliary variable, edit equation 5. Click "ok" 6. Vensim crashes 7...

Hi all, This happens consistently and unfortunately I've lost my work number times. I've used several (3, I think) versions of Vensim over the last six months, and it's been consistent across all versions. I'm now using Vensim v9.2.3 and macOS v10.15.7 (Catalina). I've saved a copy the log file prov...

Thank you for the response. Can you please help me understand your comment? The scenario that I'm trying to achieve: - Person A is exposed to an STI - There is a delay of between 7-21 days - Person A is now infectious So my intuition is that I want to implement a delay after they are exposed, but be...

Hi all - a quick question about units and the Delay Fixed function: I understand that the output units for the Delay Fixed function must match the input and initial. I also understand that for the flow variable in the SIR model, the units should be "People/Day". However, implementing a Del...

Thank you for the response. Yes, I think a summation of the infected (diagnosed + undiagnosed) is appropriate. I also think I need to incorporate the undiagnosed into that equation. I believe you are also correct about the Avg # of Sexual Partners. I've updated as suggested - noting that the equival...

Hi all, My name is Maxx, I'm a second-year post-grad studying Complex Systems at the University of Sydney. I'm using VensimPLE to model the game-theoretic relationship between uptake of PrEP and HIV/STI prevalence in the Australian state of New South Wales. Last semester I successfully developed a m...
