Hello,

I am using the new sketch style in Vensim 8.2.1, however I cannot find the function to view the model as text.


It used to be in the menu bar in View > As Text. Has it been moved to another place or is there a shortcut to open the text view?

OK, thank you!

Is there a way to have Vensim save simulation results as single precision numbers, even though the DP version of Vensim is installed? As far as I can see, there has been no SP version released with version 8.2.1 and newer. The simulation size of over 1 GB fills a local hard disk with 250 GB of space...

Ok, thank you!

I am trying to get the DLL-examples delivered with Vensim 8.2.1 (64-bit) to run in Microsoft Excel 2016 (32-bit). The example I am using is C:\Users\Public\Vensim\DLL\excel97\VENDLL.XLS When I run the "Get Vensim Info"-macro, Excel is returning a runtime error errorcode 53 - vendll32.dll n...

The difference may also come from me operating the stopwatch late in the evening, so it could be less

I will check it again.

Must be either different compilers, or optimization settings for the compiler. Are you using the same compiler on both machines? And the line beginning "cl" in mdl.bat, what /O switches are on each? Machine 1 is using Visual Studio 2010 with compile statement CL /c /I "%2" /DWIN...

Sorry for the delay, I didn't get to test it again until yesterday. I could figure out that the compiled simulation wasn't working due to a wrong configuration. In the vensim settings, I configured a mdl.bat which pointed to the wrong location in the Visual Studio\bin directory. I got it to work now...

Thanks for your help @tomfid and @Administrator.

I won't be in office until tomorrow to try out the tests you recommended. Once I return there, I will test it.

This is the output I get in my cmd-window. Did I do it as you intended?

I have been unsuccessfully trying to configure Vensim DSS 8.0.9 x64 to simulate using the MS Visual Studio 2012 compiler. Here is a screenshot of the error message that is produced: error.png I worry about "The specified configuration type is missing. The tools for the configuration might not b...

Hello everybody,

we are currently using different Vensim versions in our company like 6.3E, 6.4 and 7.3.5. A project partner is now thinking to get Vensim 8.1.2 to use and edit the models that we develop together.

Can you tell me if there are any compatibility issues to expect?

I would prefer to be able to load a .mdl with the DLL. This is a security feature. Loading a MDL would mean someone could use PLE to generate a model (or even just a text editor), and then all the advanced features of DSS (optimization, sensitivity etc) via the DLL. I see, that makes sense. Thanks ...

Thanks for your help!

I was able to create a .vpm with FILE>PUBLISH in a command script, call it from Excel-VBA and then append the subscripts to my variables like I wanted. It solves the problem, but still it is not very comfortable. I would prefer to be able to load a .mdl with the DLL.

I tried that already and could successfully append the subscripts to the variable names using vensim_get_varattrib after loading a .vpm file. However, that method returns -1 (error or no variable found) when I don't load the model using vensim_command(SPECIAL>LOADMODEL|...) earlier in my VBA-script....

I'm guessing you are looking at descriptions of the commands. The DLL will not load a MDL file. I see, thanks for your help. I guess I misread the help file since I'm a bloody beginner to Vensim. Can you share the commands you are using? And a screenshot of the export dialog in Vensim? Of course: F...

I found it in the Vensim.chm help file in section DSS Reference Supplement > 5 Command Descriptions > SPECIAL > LOADMODEL|mdlname . Is it possible to read a dataset for a variable including all subscripts in Excel-VBA using vensim_get_data() ? When I export a dataset with Model > Export dataset... i...

Hello everyone, I am using Microsoft Excel 2016 with VBA macros to import data from Vensim runs (*.vdf) with the 32bit Vensim DLL. The variables that need to be read with the vensim_get_data() method are stored in a savelist (*.lst). Additionally to the base variable names, I need to retrieve the su...
