Orbiting Particles

Problem Background

This is the problem of two sink particles orbiting each other. In this particular problem set-up, the particles are in an oscillatory orbit in which they pass through each other.

Reason for Test

This test is run in order to verify that sink particle interactions are working properly, and also that self gravity is working correctly.

Results

The new chombo can be verified by comparing it to the particle gravitational potential in the reference chombo. You should see a circular potential well in the middle of the grid. This corresponds to the center of mass of the two particles.
