Run Experiment on model start

Hi All,

Is there a Flexscript command that run the Experimenter? I've tried applicationcommand("runexperiment"). It doesn't seem to work.

I would like the model to automatically start running the experimenter upon opening. If I use go(); or runfunction(); it would only run the model once while the experimenter is set for multiple runs. I'm doing this to automate the model runs so that the variables in the model can be changed based on Flexsim's output and input from another program.

Thank you in advance for your help

Dear Pongjetanapong,

The attached model is done on basic Flexsim, which may help you to solve your problem.

Thanks arunkrmahadeva,
Your model works well!
But I have some doubts about your codes.
I comment the code in line20-23 out, and it still works well.
I put this code in other trigger and try to use breakpoint to find out what is "runstatus", while it seems to be nothing (as shown in the pic below)

Would you please tell me what these codes use for?

He copied that code from the OnPress on the Run Experiment button.

Outside of that location, those lines of code won't do anything. They are updating the "Experiment Status" window that shows the progress of the experiment run.

You don't need those lines of code to run the experimenter programmatically.

Hi All,

Thank you for your contribution. I've tried the codes but it doesn't seem to work on Flexsim HC. It does seem to activate the experimenter but the output files are not generated.

Actually, just applicationcommand("runexperiment") would do the same but still does not produce any output files

If you want the experiment to generate output files you need to activate the output. There are 2 ways to do this. Either check the "Save output files for each replication" checkbox on the experimenter or go to Statistics > Output Raw Data and check the "Activate" checkbox on the GUI that pops up. This GUI will also allow you to specify what data is exported.

Hi Matthew,

Thank you for your suggestion. I did check the "save output files for each replication". It didn't work. Flexsim and Flexim HC are quite different.

Hi Phil,
I found the following code in the On Press command of the Run experiment

Could you please help explain to me how I can get a reference to the node "c" so that I can use it in the On model open trigger? Is it possible?

applylinks(ownerview(c));

treenode expfolder = node("/Tools/Experimenter", model());
treenode exec = node("MAIN:/project/exec");
treenode reps = node("/replications", exec);
treenode runstate = node("MAIN:/project/exec/replications/runstate");
int nrscenarios = get(node("/NumberOfScenarios", expfolder));
int nrreps = get(node("/NumberOfRunsPerScenario", expfolder));
set(node("/NumberOfScenarios", reps), nrscenarios);
set(node("/NumberOfRunsPerScenario", reps), nrreps);
int statehistory = getbundlenrentries(node("MAIN:/project/model/Tools/Output>variables/DataBundles/StateHistory")) > 0;

if(getbundlenrentries(runstate) == 0 && !statehistory)
{
buildnodeflexscript(expfolder);
applicationcommand("runexperiment");
}
else
{
applicationcommand("killexperiment");
clearbundle(runstate);
applicationcommand("reset");
}

treenode runstatus = node("../RunStatus",c);
setvarnum(runstatus,"initialized",0);
function_s(runstatus,"Update");

applylinks(c, 1);

c is the view that is executing OnPress. In the OnModelOpen trigger, you can't reference the Experimenter view because it might not be open.

Activating the output will generate output files, maybe you're not looking in the right place? I've attached a model made in HC 5.0.4 where the experiment runs on model open and a Patient History csv file is created for each replication. These csv files are created in my FlexSimHC 5 Projects folder. You might need to change the output directory in Statistics > Output Raw Data.
