Problem Background

For information on the Bonnor Ebert sphere module and how to initialize a BE sphere on the grid, see BEmodule. For analytical background, see BonnorEbert.

Reason for Test

This test is run in order to verify that a Bonnor Ebert sphere is properly initialized on the grid, i.e. that a sphere is initialized and maintains hydrostatic equilibrium while being in pressure equilibrium with ambient medium.

Results

Original Test

The new chombo can be verified by looking at the density of a 2D slice through the center of the sphere. In this test, the sphere relaxes slightly around its initial equilibrium value. It is not to expand or contract without bound.
