Hello Everybody, I have a question about the internal working of the doLoop() method together with the -repeat option. The manual (e.g. 4.2.1) seems to say that only once an instance of my model is created and then the repetitions are done inside a loop that repeatedly calls state.start() and state.finish(). However, when I run my simulation it seems that in reality for each repetition a new instance is created (i.e. the constructor is called) that is run until the end !? I would like to do multiple runs and collect information from each run, which are then analysed at the end. But if each time a new instance is created the variables that hold my data are reset... I also noticed that the doLoop() never returns. Does this mean that the program is actually terminated (after the last repetition) inside the doLoop() ?? That also makes it impossible to perform calculations on collected data at the end of the simulation !? Any idea what I'm doing wrong? Many thanks, Axel
