Can you run this model [In Experiment] for me? Please.

Hi, I have this model, from a friend from college, we tried to run it using the Experimenter feature, but my pc ran out of ram (8gb) and we weren't able to generate the html report file. I was wondering if maybe anyone could run it for me and send the report file.

I used a Core i7 4790 (non-k) with 8 gb of DDR3 RAM.

experimenter.fsm

Thank you.

Have you contacted your friend's professor? You should let the professor know you were having trouble exporting the data from the experimenter.

Also check to make sure windows is up to date. There shouldn't be anything wrong with your system set up, but there could be some setting that's getting in the way of your export.

If you're running out of RAM because of too many concurrent replications, you can try limiting how many replications can run at the same time.

You control this from the Experimenter interface (main menu > Statistics > Experimenter):

From the Advanced tab, scale down the Max Cores count (0 doesn't really mean "use zero cores". Instead it means "use as many cores as my computer has").

You can guesstimate how many concurrent replications your computer can handle at once by doing the following:

  1. open Windows task manager (Ctrl-Shift-Esc)
  2. open FlexSim (if it isn't already)
  3. open and run a single instance of your model
  4. watch the RAM utilization of the FlexSim process throughout the course of running the simulation model to completion.
  5. keep note of the max RAM you saw used by the FlexSim process. Round up to the nearest Gigabyte.
  6. Let's say for example you need about 3GB RAM to run your model. In this case you should set the Max Cores to 2, since 2*3GB is under your 8GB threshold, but trying to run 3 instances would exceed your machine's 8GB of RAM.
