Hello,
The hd of the computer that was working with my model burned and had several unsaved changes, I wonder if there is any possibility of accessing a model developed in another computer?
Is there any backup that is saved through my license?

Export
Hello,
I'm trying to export data from vensim to excel, however, I have a series of 420491 data and I'm only managing to export up to 65534. Do you have any export restrictions on vensim? Is there any solution for me to be able to export all the data?

Graphics Axis
Good afternoon,
Could you please tell me how do I change the axis of the graphs of the results presentation? I'm looking for Vensim's help, but I could not answer the question.

Re: Search excel
Good Morning,
The numbers in the table are constant; they do not vary throughout the simulation. How can I use a lookup table, which function. Attached to the worksheet.

Good night, I would like to know if there is any function that can do research in excel. For example, I have the wind speed entering a variable that is the power curve (which relates wind speed to output power) and needs to get output power. The power curve is in excel on a table, according to the p...

Re: Transform annual data into monthly cumulative data
Sorry for the nuisance again, but there is some function that takes values over time for a given variable and provides the mean, for example: variable X = 2,4,3,5,2,2 desired variable = 0,3,0,4,0,2 In this case the average of the variable X is calculated every two time intervals and presented.

Re: Transform annual data into monthly cumulative data
Yes, but from this variable I need to find the maximum value that another variable reaches during the month. This new variable must compare the value at time = 1 with the value at time = 0 and so on, always providing the maximum value.

Re: Transform annual data into monthly cumulative data
I need to find the maximum value of a variable every month, however using SAMPLE IF TRUE this variable is accumulated and this is not what I need. What function could I use, having the variable that tells me when it starts a new month.

Re: Transform annual data into monthly cumulative data
The template is attached in the Fatura tab. To give continuity in the precise modeling find the maximum value of demand each month, represented by the variable Máxima demanda faturada Ponta, with one month being 2785 data each.

Re: Transform annual data into monthly cumulative data
Working with energy demand data, this data is every 15 minutes, so every 2784 data I have a month, how can I create the variable that informs when one month ends and starts the other to be able to use the equation above and reset whenever ends a month.

I am not able to open the exams that the vensim has, it is necessary to install something to have access.

Simultaneous equations
Hello,
I have a problem with simultaneous equations involved, so I made one of the variables level, but I do not need to integrate (add) the values over time. Is there any way to use a level variable without adding values?
Thanks

sum of all the values
Good afternoon,
There is a way to make a final sum of all the values over time of a given variable. For example
Variable Xi = 1,3,4,6,0,0,4,3
Variable Yi = 1,4,8,14,14,14,18,21
I want to get the variable Y, how can I proceed?
Thanks

Re: Importing Data to Use as a Search Variable
For example,
A variable X is input for an auxiliary variable X x Y with subtype with lookup, where I will have a graph that will provide me the output Y according to input X.
I need a function for the X and Y data to be imported into Vensim.

Re: Creation of hidden variable blocks
Below is a model for example, where I would like the number of panels and the load to be inside the solar energy variable.
When it was necessary to change these variables I would go into the solar energy block and change.
I need to do this so that the model is not visually polluted as it increases.

Creation of hidden variable blocks
Good Morning,
I would like to know if it is possible to create blocks within the vensim, for example, one block of variables provides a result that is used in another block with other variables. The idea would be to hide the variables in each block.
