2-D Vector Fields

If you're looking for a Java-based simulation software, 2-D Vector Fields is worth checking out. It's a free software that lets you gain insight into the properties of vector fields. You can choose from a wide range of vector fields in the Setup menu, located in the upper right portion of the screen.

The applet displays the potential surface of the vector field with particles that follow the field vectors. You can rotate the view by clicking and dragging with the mouse. Additionally, some of the field selections have adjustable parameters that you can alter according to your needs.

While the 3-D version of the applet only enables you to work with 3-D fields, this version focuses on 2-D fields. It can display the potential surface, curl and divergence; and even showcase Green's theorem and the divergence theorem.

In summary, 2-D Vector Fields is a useful simulation software that can provide insights into the properties of vector fields. The software is user-friendly, allowing you to choose from a variety of vector fields, and customize some parameters where needed. Overall, this is a recommended software to try out.
