### Example JelSim: Projectile Motion

Here's an example simulation I created with JelSim:

### JelSim

Java Educational Learning Simulation toolkit

A pretty good general purpose tool.

Created by three Ph.D. educators.

Simple sims can be made without programming.

Advanced sims require a little programming,

but not too much as they have a "wizard" to help

with model building.

Models can be reused in different sims.

Programming required: Med

Accurate visual model: Med

Accurate underlying model: High

General applicability: Med/High

Interactivity: High

Unfortunately, it's not supported any longer.

### Virtual Worlds

### Mathematica

Mathematica, MATLAB, Excel,etc.

General purpose calculation tools that can be adapted for modeling/simulation.

Some have simulation extensions.

Programming required: High

Accurate visual model: Low

Accurate underlying model: High

General applicability: Med

Interactivity: Med

### GoldSim

### Industry Tools

AnyLogic, ARENA, Dymola, Modelica, EcosimPro, Renque, SansGUI, Simscript, etc.

Intended for real world simulations.

Most require programming.

Vary in accuracy of visual model. Some provide only numerical charts/graphs for output.

Programming required: High

Accurate visual model: High

Accurate underlying model: High

General applicability: Med

Interactivity: High

### Flash

Flash animation

Index of Examples: CMU Biology

Demonstrate change over time.

Programming required: Low

Accurate visual model: Medium

Accurate underlying model: Low

General applicability: High

Interactivity: Low

### Stagecast Creator

Animations, simulations, games.

Discrete event, Rule-based model.

Program by Example.

2 dimensional

Programming required: Low

Accurate visual model: Low

Accurate underlying model: Low

General applicability: Medium

Interactivity: High

Note: Commercial software

Creating large simulation is tedious due to mouse-driven rule construction.

Example: Sudden Speciation

### VRML

VRML (Virtual Reality Modeling Language)

3D animations in a web browser.

User can control display of different portions of the model. Example: Protein Explorer

Programming required: Medium

Accurate visual model: Medium

Accurate underlying model: Low/none

General applicability: High

Interactivity: Medium

Similar to: Shockwave Flash, QuickTime

Notes: Open standard. VRML seems no longer active and the

replacement, X3D, is still immature.
