Whatever the situation it loads in about 15 seconds.

i join another model that is much more complex and downloads excel data that loads instantaneoulsly in 0.1 second.

JJ

Hi

It loads from 10 to 20 seconds.

But before that the load was instanttaneous, in 0.1 second.

Hi i like generally when starting Vensim to automatically load the model i was last working on. this dos not work anymore. To avokd that pitfall, when i finsh to work I go to the options general and chek off and in the l'oad the last model worked on'. When i do that it works fine. but it takes a lon...

Hi Jeff

Thank you for your explanation. Working alone, I do not have to manage different people simultaneously modifying a source code that has some advantages and some drawbacks too.
Anyhow good luck for your project

Hi The display code is not viewable in the flowchart view, but if I right clkck on a variable of the view, you can view the entire display code of the variable and can change it, something that I often do; i never change anything in the text model below the warnings Sketch information etc.. What is ...

I will look at yout post to-morrow. Too late for me to think. Good day.

JJ

Hi Jeff The display code appears in the flowchart view if you click on a variable; you can modfy it ; it appears too in the model as text at the end of the list. It cannot be modified. Do you agree? What do you name a sheet? Is it what Vensim names a view? Or is it what appears when you clck on a va...

Hi

I do not understand what you mean by display code inside a model. Is it a Venapp code or a script code? Can you give a simplistic model example illustrating a model with display code inside?

Regards.

Hi i never use the vector elm map function. It is dangerous with the risk of getting values outside the range of the array, and because of its complex formuoation if used with muliple subscripts that generates errors. if i want to get the value of say the element of a one dimension vector vector[sub...

Hi

It is possible too, to use the vector lookup to build a two dimensional lookup see the function example. it was maybe not possible to do that years ago and the solution at this time was more complex. It must be too possible to build a three dimensional lookup using the vector lookup.

JJ

Hi When two variables have both an effect on another variables and these effects are independant from one another, the total effect is equal to the multiplication of both effects. But if the effects are not independant from one another then you must build a two dimension lookup. There was in the pas...

Hi

Joined three workarounds that seem to work correctly. i prefer the test3 or the test4 that are safer. the test 2 works but i am not sure in all circumstances.

Hi I have a model that behaves differently when one uses a simple simulation setting a parameter value with the set button, or is on uses the synthesim modifying the parameter value using its slider. I have included the model in vpmx format and two runs; the first run named current has the parameter...

Hi

I have found the 2019 version and now it works.

Thank you for your help.

JJ

Hi Thank you for your answer. I downloaded from your source and dwonloaded visual studio 2022, finding no 2019 version. Of course there are no files from the directories specified in the mdl;bat and of course it does not compile. When installing it did not ask me anything about c++ and no ticking wa...

I have tried to download the 2017 version but i could not find it in the microsoft web site. From where do you download the C++ 2019 compiler? It can be downloaded from different sources: from microsoft or elsewhere. I tried to download from microsoft where I am registered. Which version exactly you...

I reinstalled visual studio 2019. I did not find any question about the desktop after having unistalled the previous one. i did the same for Vensim that I uninstalled and installed again with a previous downloaded *.exe. i could not download anything from Vensim that toldk that i had alarady downloa...

Hi

i have erased the manual modifications of the environment variables.

How can I help.
I can go to the PC specialist who installed windows ans sold my computer for help. He is very keen and builds customized computers.

Regards.

JJ

Thank you for your help. I have found to set the old guy.

i mean more place for the sketch, because the old guy used less place on the screen for the tools.

Question? What current version of the visual studio to you use? there are moany of them? I have gonne to the man who reinstalled windows 10 and he tried to install the compiler. Hefound that the CL.exe was not recognized because it was not recognized as an environmetnal variable; He then decalred th...

I think so. But I will reinstall visual studio.

Hi I have found the CL.exe file in 4 directories listed below. C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.29.30133\bin\Hostx64\x86 C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.29.30133\bin\Hostx64\x64 C:\Program Files (x86)\Micros...

Hi

After the compilation fails, Vensim says 'failed to compile the model (does not exist)'.

the other warnings are in the echos of the command file I joined.
