Anylogic - Counting Variable in an experiment

Question

I am currently working on an Anylogic project related to the health care sector. In order to get meaningful results, I've set up an experiment for parameter variation with 500 replications. After each replication, my main-method should output certain data into an excel sheet. Now, in order to have a data set with 500 filled columns (1 for each replication), I'd need a public variable that represents the column number. It should be accessed by the experiment, increased after each replication by 1 and also accessed by the main method in order to transfer the next column number for the excel output. So far, I haven't found the command for accessing a variable from the simulation in the main-method or the other way around.

I hope you can give me a helpful hint for that issue.

Thank you very much.

To access the replication and/or iteration (parameterset) number in the main object (or any other Agent) you could try it like this:

Experiment exp = getExperiment();
if( exp instanceof ExperimentParamVariation )
{
    int curRep = ((ExperimentParamVariation)exp).getCurrentReplication();
    int curIter = ((ExperimentParamVariation)exp).getCurrentIteration();
}
else 
{
    //whatever you want to do in case another experiment type is running
}

For accessing a variable or method of the main object from the experiment you have to click on the experiment, go to the properties window and to the "Java actions" area. There you can specify before and after simulation code where you have access to the root variable that contains the current main-object. So if you have a certain result variable (for example numberOfPatients) in the main object you could simply access it via: root.numberOfPatients
