Modeling a bouncing ball with STELLA

In summary, the conversation discusses the difficulty in using STELLA to model the behavior of a bouncing ball, particularly in handling discrete variables. The idea of using a variable to multiply initial velocity by the elastic coefficient is mentioned, but it is found to be impossible with STELLA. However, a solution is found in an article that demonstrates how to model hybrid events with STELLA. The article is highly recommended as a resource.

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?

my first response would be to suggest exploring other modeling software that may better suit the needs of this particular project. While STELLA may be limited in its capabilities for discrete variables, there are likely other programs that can handle this type of modeling more effectively.

However, if STELLA is the only available option, there are a few potential solutions that could be explored. One possibility is to use a combination of discrete and continuous variables in the model. For example, the initial velocity could be represented as a continuous variable, while the bouncing motion itself could be represented as a discrete variable. This may require some creative thinking and experimentation to get the model to accurately represent the behavior of a bouncing ball, but it could be a viable option.

Another approach could be to use a different type of model, such as a differential equation model, which may be better suited for modeling the behavior of a bouncing ball. This would require a different software and a different approach to modeling, but it could potentially provide more accurate results.

In any case, it may also be helpful to consult with other experts or researchers in the field who have experience with modeling bouncing objects. They may have insights or tips that could assist in solving this issue. Additionally, reaching out to the developers of STELLA for support or guidance could also be beneficial. Overall, it may require some trial and error and creative problem-solving, but with persistence and collaboration, a successful model of a bouncing ball can be achieved using STELLA or other modeling software.
 

Related to Modeling a bouncing ball with STELLA

1. How does the STELLA software model a bouncing ball?

The STELLA software uses a system dynamics approach to model the motion of a bouncing ball. This involves breaking down the system into components, such as gravity, air resistance, and the ball itself, and creating equations to represent their interactions and effects.

2. Can the STELLA model accurately predict the trajectory of a bouncing ball?

Yes, with proper calibration and accurate input data, the STELLA model can accurately predict the trajectory of a bouncing ball. However, it is important to note that the model is only as accurate as the data and assumptions used in its creation.

3. What factors are considered in the STELLA model of a bouncing ball?

The STELLA model takes into account factors such as the initial height and velocity of the ball, the force of gravity, air resistance, and the elasticity of the ball's material. These factors can be adjusted to simulate different scenarios and variations in the ball's bounce.

4. Can the STELLA model be used to simulate real-life situations with bouncing balls?

Yes, the STELLA model can be used to simulate real-life situations with bouncing balls. By adjusting the model's parameters and input data, it can be used to analyze the behavior of a ball in various conditions, such as on different surfaces or with varying levels of air resistance.

5. What are the limitations of using the STELLA software to model a bouncing ball?

The main limitation of using the STELLA software to model a bouncing ball is that it relies on simplifications and assumptions about the system. This means that it may not accurately reflect the complex physics of a bouncing ball in real life. Additionally, the accuracy of the model also depends on the accuracy of the input data and the assumptions made in its creation.
