Re: Get data xls with multiple subscripts

Can you get the sample models working? They should import more than 1 subscript.

Re: Multi-input Lookup

Sorry again, I'm still under the weather. I've attached a demo model that does this two different ways. 1. Reading the values in as data. This is my preferred way of doing things, read these in as a time series and use GET_DATA_AT_TIME ("time" being the outside diameter). But that might me...

Re: Vensim not correctly calculating stock from flows

Can you provide more detail please? Looking at the spreadsheet, there are two columns titled "calculated stock value", but it's not clear to me what stock this is referring to (there are numerous stocks in the model). Also, are you including time step in your Excel calcs? https://www.vensi...

Re: Close Excel when exiting Vensim (if opened) won't stay active

Thank you.

This setting is also under the "Excel" settings window, so I'll remove it from the "General" section in the next Vensim release.

Re: Unable to open Vensim

If you've used Vensim before, try deleting or renaming the .venple file in your home folder (it's hidden).

This will mean Vensim starts with default settings, maybe you had the old GUI running before?

Re: Multi-input Lookup

Sorry for the slow reply (I'm unwell at the moment). I still just don't understand this at all. Can you try and simplify things please? Let me know what info you have, then what you need to get from it? If you have an array of lookups, it's easy to pick out a specific one which could be the 2nd look...

Re: unit conversion

Yes. Create an unchangeable constant called "kg per lb", give it the correct units (kg/lb) and value (0.453592). Then you can use it to convert any kg or lb measurements in your model.

All you should do is save your model. It should not appear once you have saved.

Re: Multi-input Lookup

I'm struggling to follow at what you are doing here. Subscripts are usually used to turn one variable into an array. So you could have a variable called "sales" and this could be subscripted by "region". I've had a go at building something simple that I think might be what you ar...

Re: impossible to switch back to the old gui a model built with the new guide

Do you have a timeline for retiring Venapps and introducing web publishing? We have a client that needs a flight simulator in Q2 2024 (preferably April vs June) and web would be a much better solution. You can already publish to the web via Vensim DSS. This gives you a model that will happily run i...

Re: where is the sim set up from the old GUI in the new one?

I'm currently travelling so don't have a computer in front of me. It's to the left of where you enter the run name. It should also have a tool tip, so hold the mouse over each button until you find it.

Re: Solving for implicit functions before starting time

The FIND ZERO function should do what you need. It can loop a section of model structure to try and numerically solve something. There is an example in the help system on how to use it (I'm travelling otherwise I would have pasted the link for you).
