It can be done by specifying "map item" entities, which are points with lat/lon.

We'll be bringing back the 3D visualizer for simpler non-GIS applications like this.

At the moment, I don't think so. I'll see if I can think of a workaround.

There are several ways to do this, depending on how large a vector of vehicle types you need. Here are two: VehicleCohorts.zip In #1, each cohort includes separate stocks of EVs and ICEs. This is pretty simple. In #2, the idea of the "fleet" is generalized so that the total market includes separate ...

There isn't - but there should be. I'll put in a feature request ticket.

There's that, but there are also some options on the scaling tab of the control panel.

That could be a graph settings issues - there are settings for tight and loose scaling and inclusion of 0. Yours might not match theirs.

Actually, you might only need Pro.

This may be necessary for situations where users have new and old datasets in the same location.

Perhaps the rule for x64 should be that the extension is omitted for the native vdfx, and shown only for the legacy vdf.

The issue seems to be the projection - MGI/Austria Lambert. I reprojected the file to WGS84 in qgis, and the result works.

The most likely candidate is a filename mismatch, or file in wrong directory.

Usually the easiest thing is to prototype your commands as a command script.

RUNNAME controls the run name, same as for ordinary simulations.

Forgot the attachment:

I'm not convinced that there's a problem. I used the attached modified model to run a sample of 1000 realizations at once, and looked at the statistics for the cumulated "input". The expected value of the standard deviation of "input" given by the binomial distribution is sqrt(100000*0.2*(1-0.2))=12...

I think you've found an aspect that's not implemented yet - plotting entities that don't exist at time 0. Hopefully this will be done soon as we need it too. It'll be in 3.0.x and we can give you access to a nightly build when it's ready.

Do you have an example for the blank-screen problem?

I'm not sure your users would need to do anything. When you run model A, the generation of a dataset is automatic. Similarly, when you run model B, it'll read the dataset specified on the Advanced tab without any intervention. Two things could go wrong I guess: - a file collision if there's a concur...

1) I assume the correct result would be for Italy to become blue at time 5. Not sure what's happening - I just ran a quick test that I think is similar and it worked. What's the time scale in the Run Control in your sample model? Can you post a copy (.zip the whole model folder, including shapefiles...

Here's a simple structure that generates pulses. There are a couple limitations - width=TIME STEP, and it wouldn't work with RK4 integration. I'm guessing it would work for your case though.

There's a chapter on the allocation function assumptions and constraints here: https://www.vensim.com/documentation/allocation_overview.htm It might be possible to do something more complex using FIND ZERO if needed. It's also possible to do allocation using the optimizer, though not very practical ...

There's some info in the Help system under Examining Results>Visualizer. A video is also in the pipeline.

Enforcing limits on the allocation is exactly what the function does. The price is really just a priority for the allocation process within those constraints. The solution to the alloc function is optimal if you interpret the priority distribution for each supplier/demander as a cost or utility func...

You want DEMAND AT PRICE, SUPPLY AT PRICE and FIND MARKET PRICE. See the sample model in the Help system. https://www.vensim.com/documentation/fn_allocations.htm

The latest covers the Vensim import feature:

See https://ventity.biz/ventity-3-0-released/ for details.

There are 3 options at present:
- Use evaluation versions or full licenses for the trial users
- Deploy the model on Forio.com
- Deploy the model on your own servers with our Windows Service component (contact us for details).

A possible workaround would be to create a macro that implements a pulse train.
