Getting value of TIME STEP while leaving out its unit
Hello all, I have a small request to which I have unfortunately not yet found a solution. There are cases in which dividing or multiplying by the TIME STEP is helpful in assigning a time unit to a variable and thereby avoiding unit errors. Example: I want to determine total cost of all annual public...

Re: Disenabling automatical adjustments of clear boxes?
It's interesting to see that others also experience these problems. Thanks for your replies! I've been using Vensim 9.3 for a couple of days now and so far the problems described above seem to have been largely solved, many thanks! Maybe there are still some minor problems if I noticed correctly, bu...

Re: Disenabling automatical adjustments of clear boxes?
EDIT: The problem described above might be related to the following: I've been setting up a new laptop and moved files over from the one I've been working with so far. However, when I open existing project files, the design of the sketch sometimes gets strangely adjusted (see attachment). These circ...

Disenabling automatical adjustments of clear boxes?
Dear all, I'm having the follwing problem in Vensim 9.2.4 (for Windows), which didn't seem to occur in older versions, if I remember correctly. At least I dind't notice this strongly... As you know, each element in the sketch is by default enclosed in a clear box whose dimensions can be adjusted by ...

Re: Variables that influence inflow and outflow rates of stocks?
Some time has passed and I wanted to give some feedback. Thank you so much for sharing the model (TranspoExcerpt.mdl). The model has been incredibly helpful!! I can hardly emphasise that enough. It was helpful and valuable both in terms of our mobility research and in terms of what I have learned ab...

Re: Variables that influence inflow and outflow rates of stocks?
Hey, many thanks for your thoughts and suggestions! I’m back at work and motivated to take up the ideas and improve my understanding.
I would be happy to have a look at that model you’ve mentioned, but can't find an attachment. Is this a problem on my side?
Best wishes!

Re: Variables that influence inflow and outflow rates of stocks?
Unfortunately, I have to come back to my problem. I have started simple and elaborated step-by-step. So far this has worked quite well. However, I realized that in some cases it doesn't make sense defining variables as stocks. For example, current “Car Usage”, at least in my understanding, does not ...

Re: Variables that influence inflow and outflow rates of stocks?
EDIT: With regard to question 1, that would also be possible for “Attractiveness for Driving”, wouldn’t it? When combining a stock “A” to a stock “B” I link the inflows and outflows and add a variable that accounts for the effect a change in stock A has on stock B. This would allow me to take more e...

Re: Variables that influence inflow and outflow rates of stocks?
Many thanks for your quick reply! This was very helpful and the idea to use some long term smoothed function makes sense to me. I already tried to implement your suggestions yesterday and have continued to work on the stocks today. 2 short questions about this: 1. Wouldn’t it in some cases also make...

Variables that influence inflow and outflow rates of stocks?
Hello everyone, I’m a researcher from Germany and system dynamics modeling in Vensim, which I’m becoming more and more enthusiastic about, is new to me. I have encountered many of the excellent sources for learning and now have a question that came up while developing my first model. As a start, I w...
