"Out of Memory" error in Embed

When I expand my simulation periods, the Embed gave me an error message "Out of memory (requesting ... kBytes)". See attached pitture. But I suppose my computer memory is bigger than what it demanded (1.5e+4 kBytes). How can I solve this problem?

    How much memory do you have on your PC?

    How much memory do you have on your PC?

    I have a total of 16GB memory, and usually there remains about 8 GB memory

    It's a weird error message. Requesting only 15 MB :(

    Yes... And if I remove the figure monitors (2D plot), it can run successfully. Maybe it's because I have too many monitors?

    I found that when I delete the export txt block (Blocks - Signal Consumer - export), the problem solved. Maybe it's because the output things are too much (120 variables, each variable to export 20000 value). But I still want to export these modeled results, is there some solutions?

    When I tyied to change some attributes of this export block, "negative" out of memory error occured, see Fig below image

    What is the time step you are using to export the values ?? Please attach the diagram/file you are facing an issue .

    Hi Girish, here is the export file panel which is labelled as red. Since I ran a 50-year simulation, the Endtime is 365*50 = 18250. Is it because 18250 is too large? But I have to export these data points...

    By the way, I found everytime I changed the simualtion period, the "Fixed Interval" always changes automatically to the "Step" (0.02 here). But I want it to be just "1", so I have to change it every time (I have many export blocks). Can I make the Vissim not change my "Fixed Interval"?

    Hi everyone, here is the solution: I deleled all the plot blocks in the model, then this error doesn't occur. In other words, this error has nothing to do with the export block: it's because of too many plots. See also the help file where it explains why plot block may cause this error.
