Hi Kong17 As a client, the administrators are kind enough to study your model. But as you are not a client of mine, I can advise that before wanting to do sophisticated things, you should first learn simple but mandatory ones. Put on the settings unit, the use strict testing to on, and put dimension...

HI I finally found the reason. It is not because of the drive that I changed to a SSD, but because of the RAM that was only 4 gigabytes. I changed to a 12 gigabytes and it saved in 40 seconds instead of one hour and a half. In fact it is necessary to have a RAM that is at least bigger and probably a...

Hi

I have already run a model and saved data on a new .cin file and tried to edit afterwards. it still does not work and exits Vensim.

.cin file can be modified using other Tools. So it is possible to manage although cumbersome. i will too ask my technician if he can find Something.

Regards.

Hi I talked to my technician. He says that changing to a solid state drive will may be increase the speed by say 30% but will not have a significant effect. When i run with a parameter value of 8, and a file size of about 2.25 it takes 30 seconds and with the value of a parameter of 16 and a file si...

The only reason of wanting to keep the 7.3.5 version is if there is by lack of chance something critical not working with the 64 version. Otherwise I have no reason to keep the old version, especially as you can run the old models without any change. I will wait a bit before building a different com...

the path to the .cin is c:\nouveau rent\simple_135\simple\cas1_période pleine.cin

I send you by mail the ini file

JJ

with the 7.3.5 single precision.

Hi

Now when i try to compile with the 32 version it says 'failed to compile the model (version mismatch got 52050 need 51050).

Regards.

JJ

HI

When I try to edit a file, say a *.cin with the edit file it does not work and exit from vensim. It works well with the 32 edition.

Hi

Sorry the first view where the constant has to be changed has the name 'paramètres de base'

Hi

I join the model. If you run it as it is it takes less than a minute to save. But it you change the value of the constant 'niveau de la demande totale par jour' in the first view 'programmation dynamique' from 8 to 16 it takes one hour and a half.

Hi Tom

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?

Regards.

JJ

It is still not working. there is a message : Compiling Vensim model … Setting paths for Vensim compilation using Microsoft compilers Visual Studio 10 The specified configuration file is missing. The tools for the configuration might not be installed. Creating optimized DLL. ‘CL’ n’est pas reconnu e...

I do not know which bar file to use: the old mdl;bat or the new one mdldp64.bat or maybe with changes. They are both in the right place users/public/vensim/comp

JJ

Hi i join the old mdl.bat that called a C compiler version 10. i do not wher to download the latest 2019 version. On the Microsoft site there is a visual studio 2019, but it is not free, more than 300 dollars. But if I use the old mdl.bat the compiler saus that it does not find the paths. Regards. JJ

Hi

i suppose taht the right file is named MDLDP64.bat. It calls files that i have not. I used an old visual compiler not the 2019 one. I will down load it and see if it works.

Hi

i have downloaded the 64 version. But the compiling does not work. I have still the older mdl.bat. Where is the 64 bits mdl;bat situated?

Regards.

JJ

Hi Tom

Thank you for the information. I will download the 64 version. if anything goes wrong i will inform you.

Best regards.

JJ

Hi I am currently working with the 32 bits Vensim DSS version and think about migrating to the 64 one with the minimum of problems. What are the current problems encountered when migrating? I did not find any information about that in the Vensim documentation. Is it running at the same speed and if ...

simplify your problem. Start with two plants and simplify everything else that can be simplified. Once the simplified solved, add one by one what you have substracted.

Hi

The basic for good modeling is to have no unit errors; If you set model>setings>use strict testing' it will tell you your unit errors. Correct these unit errors and it may help you to find the other error.

Regards.

JJ

HI

Goto model, settings and change units and check 'use strict testing' and afterwards test unit dimension. you will see 7 unit errors. Correct them and it may reveal your error.

Regards.
