Hi, Is there a way in Vensim to have all the equations perfectly edited so that they can be paste easily in Word? For example instead of having something like that pasted (with tags, alineas and unwanted space everywhere): (002) "actual cash-flow margin"= XIDZ(total cash commitments on deb...

Everything is back to normal now (the problem occured only once with winXP (at least for the moment): the first time I opened the file. I do not have any external data. Maybe a problem with win98 (Vensim has not generated the problem anymore with winME since I use the files saved while working with ...

You need to click on "set" (for setting a simulation) and then on the left you will see "Euler" written. By clicking on "Euler" you can switch to "RK4." This is the only other method available in PLE Plus.

I have just tried on WINXP: same problem...

I was using WIN98 at my office (the computer has been changed today so now I have WINXP) and at home I use WINME.
The error occured both on WIN98 and WINME.
I tried to open directly from Vensim but it did not help.

I use PLE Plus 5.4b The exact directory of the file is: C:\My Documents\Work\PHD\Thesis\model\Financial Fragility developed.mdl And there is also: C:\My Documents\Work\PHD\Thesis\model\Financial Fragility developed with MP.mdl I just need to put the files on the desktop and I can open them. If I the...

Hi,

I have a Vensim PLE Plus file that does not open when it is located in the folder C:Model but does open when I put it into another folder.
The error message is that venplep perfomed an illegal operation.
What's wrong?

Thanks

Thanks. It is a theoretical model for my thesis (will be developed during post doc). I would like to have the pro version...but I am a student and it is way too expensive. Hey! Vensim Guys! What about a student version...Come on!!! Anyway, I can work out the complexity (the model is actually very si...

I forgot to provide you with a few comments. What you need to look at is the variable named "last max value of the cash flow margin." It is the on the left side of the "Private investment demand" page.

Hi,

I attached the model.

Contrary to you I think that SD and economics are totally compatible. The problem is at the level of economists: they usually do not take into account all the stock and flow implications of their model, which is in fact crucial for the dynamic of the model. Godley and Lavoie (see cambridge journal o...

Allright guys, I have tried both of your solutions and the "sample if true" function works best. What's weird, however, is that it works in PLE Plus (I checked the guide and, as one of you noticed, this function is normally not available in PLE Plus...but the model runs!). The stock soluti...

Ok but it is not what I would like to do. I know those functions. What I would like to be able to do is to go back to the last value of the ratio that was not zero (or better the max value of the ratio) so that if for example the ratio is 5000 at a moment it does not drop suddenly to 0 or any other ...

Hi, In my model I want to be able to calculate a ratio x/y even when y = 0 (y cannot be negative in the model) . An easy way to do this in PLE Plus is simply to take the previous value of x/y but if y = 0 for two periods in a raw this solution does not work and I am forced to put a value for x/y tha...
