to PJ: You can work with a Check Box using its API or placing a code in the Action section. Please refer to the Help for more detail. You can change a model's parameters in the similar way as done in the model 'Bass Diffusion'.

Victor, Are there any examples you can provide of setting up a simulation to allow the user to set model parameters based on a check box or radio button from the simulation pane (i.e. before the model is running)? I see only the use of sliders in the Bass Diffusion example. Many thanks,

Hi PJ, I am a beginner in AL but I have been able to setup models where the parameters are chosen on the Simulation panel before launching the run. Here iw what I do in AL 6.2 (the details have changed between 6.1 and 6.2): If your Main has a parameter called L0 and you want to set the value of this parameter by reading a textbox before running the model: Getting the value of the textbox before beginning a run (even if this value has been modified by the user): Put in the "Before simulation run" box of the Advanced tab of the experiment (for reading the value of L0 in the example, from editbox_L0): Double tmp = new Double(this.editbox_L0.getText()); double xx = tmp.doubleValue(); root.L0 = xx; This will set the value of the variable L0 of the class Main. You can also use computations for setting these values : root.L = 2*root.L0 This method can probably be used to read the value of a checkbox and initialize the model in consequence. I was surprised that this possibility is not at all discussed in the help file given that such a functionality seems quite standard to me... I hope this helps. Murat

Murat, Thanks for this. I've tried your code and it works perfectly! Cheers, PJ

You are welcome! :-) I think that the help system should have a "How to" section that covers this kind of information... Anyway, I am taking notes during my learning process and I will probably later post a AnyLogic Tips page on my web site. I think that AL is a very beautiful software but its learning curve is quite steep... Best regards, Murat
