Something strange is happening with phi. The dipole term isn't supported in 2D for the multipole expansion BC's, but would expect a symmetrical distirbution such as this would be good to go, given it should only have a monopole term… Here is a movie of phi.
Here are where the sinks are forming:
The initial sink:

Here is rho final, zoomed out:

Phi looks better???
