Using Material Properties in Equation

Hi, I am trying to build a gravitational potential simulation to investigate Roche limits. I am using the Poisson's Equation module to model Newtonian gravity. I have built a simple geometry of the Earth and Moon as spheres, each with their own densities, rho, and a large block of space of 0 density around them.
In the source term, I have f=4 * pi * G * root.material.rho
It is returning a seemingly homogeneous field, pictured here. I am thinking that perhaps I have used the wrong syntax and it is not reading the density of each material to calculate the potential. Can anybody help?
It may also be that I have not specified the correct boundary conditions. If anybody has any ideas, please share. Thanks for your help.
Edit: Found the Dirichlet Boundary Condition setting and that appears to have fixed it.
