VSim Examples

Overview

These are examples for illustrating the capabilities of VSim.

VSim [VSi] is an arbitrary dimensional, electromagnetics and plasma simulation code consisting of two major components:

• VSimComposer, the graphical user interface.

• Vorpal [NC04], the VSim Computational Engine.

VSim also includes many more items such as Python, MPI, data analyzers, and a set of input simplifying macros.
