It would really help if you uploaded a model demonstrating what you are trying to do (and where it is going wrong). We would need to take the time to generate it ourselves from your description, but there is a good chance we would get it wrong.

Are you on Windows or mac?

Are you running Windows 7? Windows 7 is no longer supported.

Yes, definitely. The extra RAM would mean that results are stored in memory rather than a swapfile on the disk which is much slower.

I think that's a question for the MS teams folks, seems a regularly searched term on the web.

Remote access is fine, a remote machine is no different to a physical machine.

The dll is only provided with Vensim dss

I don't have any problem opening that file.

A quick search on Google will give you other opinions. https://www.laptopmag.com/articles/help-me-ssd-upgrade-budget-laptop (When we ran our LAPTOP File Transfer Test, which involves copying 4.97GB of files, the hard drive operated at a rate of 33.9 megabytes per second while the SSD hit 237.8 MBps,...

Solid state drives give a huge boost in performance, it's much more than 30%.

The model saves on my machine in less than a minute.

I tried this experiment. Time step changes when you set "niveau de la demande totale par jour" meaning the results file is twice the size of the original. So it will definitely take longer to save. Mine still saved pretty quickly though for a 4.5gb file (but I am running a solid state drive). What k...

I've tried both the INI files, and am not having any problems with the text editor.

Would you be able to send the CIN file to us?

Also, how are you using it? Are you using a button on a custom toolset or File->Edit File?

ok. If you want to keep 7.3.5 and 8 of Vensim you also need to have two separate COMP folders. The compiler has different settings for 7.3.5 and 8.

Are you trying to compile with an older version of Vensim?

I use it all the time. Can you email your vensimdp.ini to us (vensim@vensim.com) to test with please? You will find it in %APPDATA%\vensim

Also, what is the full path of the CIN file you are trying to edit in case that is the cause of the problem?

Can you use the MODULO function?

I downloaded the 2019 version with the 'ticks'. The compilation works fine and the time to save up to 2 GO was OK. But it took more than an hour to save a 4.5 GO file! Is it normal? It could be normal depending on what hardware you are using. If you want us to test here, feel free to email the mode...

You can select either BAT file. What you are actually doing is selecting the path to the file, internally Vensim will call the correct one to compile the model.

During installation, the default is to leave the comp folder intact. So you might need to reinstall but tick the box to install compilation files.

I'll change this for the next release as the old comp files should never be needed again.

There have been a few threads on the forum regarding this. Have you looked though those to see if they help?

I'd use subscripts. Here is some Vensim structure that will allocate the hydro generation on a proportional basis to all 200 units based on their relative demand. unit : (unit 1-unit 200) demand[unit] = 200, 300, 400 etc total demand = sum(demand[unit!]) relative demand = zidz ( demand[unit] , total...

I don't understand what you are trying to do.

Are you trying to allocate the hydro generation to something?

(It would be nice if the Vensim download center stated that only windows 10 is supported, it would have saved me a lot of time )

We do list the hardware/software requirements on the FAQ at
