Get a faster computer. In all seriousness, the question as you ask it is very difficult to answer. One piece of advice: Run the profiler, look what pieces of your code consume the most resources, and then ask a more specific question in the forum.

For a better answer see Walter's link. In general, however, models will vary in running time depending on complexity and simulation time. If you set the run time to inf it will never stop!

There's a lot of potential answers if oyu supply more info.
