make compile && ./pcuditas_main.out or simply make run.
You can check other examples of simulations in the examples/ folder.
For example, here is a screenshot of a random walk in GPU:
Also, each file has it's own tests. Those are written in such a way that they show how to use the code. If you want to become familiar with the internals of the program, that's the best way.
For example, here is a sample of the tests for the EuclideanVector class, from
the file pcuditas/vectors/EuclideanVector.cu.
