Download the models and simulations found on the Samples page (for instance, a few basic examples can be found here
Run the applet. You will be asked to accept a certificate (the applet will not run unless you accept thet certificate).
Select the output file containing the results of a Cell-DEVS simulation (for example output.drw on the sample models above
Select the Coupled Model file (extension .MA), which defines the model specification used for that model. The applet use basic model definition found there to draw the model grid (for example, choose FireII.ma in the example above).
Select the intervals chosen for each of the output values. Each range of values correspond to a different color that will be used to display the cell's values. The ranges can be defined manually or by selecting the predefined ones.
Select the colors manually or by selecting the predefined ones.
