Ventana software support forum

Ok, here's a clue that could help us figure out what the problem is: The problem disappears when I turn off "show_underbar" in the settings! So it is likely somthing related to the underbar feature. Both graph tool and table tool work in this case. The problem is that we can't do that beca...

(created with long gone vensim versions) I'm still puzzled that the table is showing only "D". Does a variable or subscript called "D" exist? How is the workbench selection being made - click on diagram, in a table or graph legend, or in the variable list in the control panel? N...

I have tried saving as vmfx (after doing reform and clean), to no avail.

I have now noticed that the issue also exists in the graph tool (see attachment). Interestingly here, the variable name is neither correctly displayed in the title bar of the window nor in the title of the graph, which is what you had asked for regarding the table tool. Does this give you any clues?...

The name of the variable is corretly displayed in the title bar of the vensim window and in the title bar of the table window, but not in the row of the table itself. I have now created a new model and then the problem does not appear. Hence, there must be a something in the model that we are workin...

The table tool in Vensim 9.1.1 does not show any variable that is clicked. It only shows the name of the run and then all values are given out as being zero. See attachment. Note that a run is loaded and I have tried several variables. I wonder if others have the same problem.

The issue remains under 9.1.1, plus I found a bug in 9.1.1 in the Table tool, will report that in a separate thread though.

I have tried to save the model as vmfx and then created a history run, and then tried to run a scenario of the future using based-on. Error: "Insufficient membory for block allocation to be made". Sometimes Vensim even crashed (Vensim 9.0.0 only, but not always).

Yes I am running the 64bit version. Would an undiscovered size limitation bug mean I'd have to wait for an update to get this fixed? Please also note that there seem to be problems with using based-on in compiled mode. I assume you tried a 64-bit version? In that case, there's probably an undiscover...

I have created a very simple model for test purposes (attached). I am not getting the error described above any more, but it seems it works only in uncomplied model (setting "interpret"), but not in compiled mode. Is it generally the case that the based-on feature does not work in compiled...

No, unfortunately I can't, because the company I work for is seeing this as intellectual capital... Is there anything we can do in terms of trouble-shooting without the model? It is in .mdl format by the way, which I had forgotten to mention.

I would like to run a (large) model using the "Based on" feature of vensim. I have created a history run, that goes up to a specific year and specified that file under Sim set up "based on". When I try to run it like that I get an error: "Fatal error from Vensim Insufficient...

I can't get a script to work, because I don't know how to correctly put the code. I have read in the help files that I am supposed to use quotes around the command if I have a subscripted variable. I am not sure what that means, specifically, what to include in the quotes (you may wanna clarify this...

I have some commmand scripts that run fine in Vensim 6.4 (x32) but that do not run in Vensim 8+ Have there been any changes to syntax? Or the way that the syntax is interpreted by Vensim? Is there a documentation on these changes available? I am attaching an example. In Vensim 8.2.1 I get an error m...

When updating to Vensim 8.x the resulting simulatin files (vdfx) are roughly double the size than when I run the same simulation in an older Vensim version, generating a vdf output. For us this is relevant because due to model size, the old ones were slightly above 0.5GB now they are above 1GB... Wh...

Same for MENU>VDF2XLSX by the way

The vensim documentation for MENU>VDF2XLS does not mention a possibility to specify in the command script the sheet in the xls file into which the data is to be exported. Is there a way to specify this? By the way: there is improvement potential in this documentation as it states tabfile instead of ...

Example variable: Energey efficiency of Trucks: conventional Trucks units [liters/km], battery electric Trucks[kwh/km], Compressed Natural Gas Trucks [kg/km]... Is it possible to have subscript elements that are conceptually basically the same but use different in units? Of course I am aware that th...

Thanks for considering adding this as a feature.

I like SDMDoc, but in my experience it does not work for large models, it crashes when applying it to large models.

In big models with many views and subscripts, it is sometimes cumbersome to find if two variables already have a causal connection. Is there an automated way of doing that similar to the loops tool in Vensim? I would imagine the output to be a list of causal chains with the two variables at beginnin...

is it possible to apply the type of settings that I can apply to a variable when I do a right click (contextual menu) to several variables at a time? I need to merge two models in one of which aux-vars have used the setting "clear box" whereas the other model uses "none". Hence I...

I have to correct myself, I actually got it to work with the help of a colleague!
Here is my example code:
MENU>XLS2VDF|..\another_subfolder_to_parent_folder\SpreadsheetWithData.xls|..\Data.vdf|..\another_subfolder_to_parent_folder\FormFile.frm|sheetname

In a command script the relative file paths can use sub-folders by using a forward slash "/" This works well. Is it also possible to go a level higher to a superordinate folder? Let's say I have a folder wich contain my command scripts that is a subfolder to a folder which contains an exce...

Have done a search for \_ or \<space>. No hits.
Any further ideas?
