Modeling a bouncing ball with STELLA

Click For Summary
SUMMARY

The discussion focuses on modeling the behavior of a bouncing ball using STELLA, a system dynamics software by ISEE Systems. Users have encountered challenges in simulating the bouncing motion beyond the initial cycles due to STELLA's limitations with discrete variables. The conversation highlights the need for a continuous modeling approach and references an article that successfully demonstrates hybrid event modeling in STELLA. This resource is essential for users seeking to integrate both discrete and continuous variables in their simulations.

PREREQUISITES
  • Understanding of system dynamics modeling
  • Familiarity with STELLA software
  • Knowledge of continuous vs. discrete variables
  • Basic principles of elastic collisions and motion
NEXT STEPS
  • Read the article on hybrid event modeling in STELLA
  • Explore STELLA's documentation on continuous modeling techniques
  • Investigate alternative modeling tools for discrete event simulation
  • Learn about integrating discrete and continuous variables in system dynamics
USEFUL FOR

This discussion is beneficial for system dynamics modelers, educators in physics and engineering, and anyone interested in advanced simulation techniques using STELLA.

Does any of you have an idea of how to model the behavior of a bouncing ball with STELLA (ISEE Systems)? I have only been able to get my model to show correctly the first two cycles of the bouncing motion.

My idea is to have STELLA to plot the first cycle and have a variable to multiply the initial velocity of the movement by the elastic coefficient e, but it seems it is impossible for STELLA to have a variable to be incremented in a discrete manner, only continous.

I have searched Google and found nothing. Could it be that STELLA can only be used to model time-continous variables and cannot handle discrete variables?
