Do you have any experience of programming? If yes, you should be able to figure out what the error is here. If you do not have any experience of programming, it would be a good idea to search around Google for a tutorial. The following is the reason things are not working for you. But as I said, if...

I'm trying to experiment with the EXCEL97 file listed in the DLL folder. I'm having problem of compatibility since i'm using win7 64 machine. The vensim folder is stored in program files (x86) while the VenDLL32 is stored in C:\Windows\SysWOW64. Now, when i try to run the EXCEl97 file, i get this er...

Thanks Tom, I'm going to use VB.

Hi,

I would like to do some programming work using using visual studio. I have read some of the thread and i concluded that the code might not work or will have some errors with advanced version of visual studio. So which version of visual studio works well with vensim 5.2a

Thanks

I have to analyse different scenarios in the SD model i developed. Now, is there any method to neglect the influence of some variables? I do it manually be removing the arrow connection, run the model, then add it again.

Any suggestions

Those are just backups. If you want to hide them, you can set up a backup path in Tools>Options>Startup. ThanksTomy, Are all the variables in the model can be changed in the venapp application? I see some variables in my model are not on the list while inserting in the app. I guess only constant va...

Hi

You only need the one file, the VCD. It's easier to start with an existing VCD file, if you look in the help files/models that come with Vensim, you will find a few examples. Start with one of these and modify it. And rest of the files will be created automatically when i work with VCD, that's what...

Generally that means that you've defined the variable with one set of subscripts, but used it with another.

You will need to debug the model to figure out why the end values are incorrect. My guess is that it is something to do with IF THEN ELSE( Work Done[task] >= 0.98 * TASK SIZE[task], 1, 0) Please accept my appreciation for the great and prompt support...You are right...the problem is with 0.98..

See the attached model, this does what you need. Tony. Hi Tony and Administrator Please refer to PROJ3 model in this thread. Task size 14500, 29200, 192700... Total=236,400 After running the model and computing the final total work using function SUM( Work Done[task!] ) i get 235,000....why is that...

Why don't you try to simplify your problem and model, (say two levels or even one). There are two advantages: one is to make your problem easier to solve, the second is to attract more people to help you.

Thank you for your respond and caring .

I got the problem solved.

In model 2, your arrangement of the chain implies that "spreading rate" reduces "dumping done". So the meaning of "dumping done" is really "dumped but not yet spread". A possible fix would be to change the equation for "task is done" at each stage t...
