Update Gravitational Potential including indirect terms authored by Elena Lega's avatar Elena Lega
The gravitational potential entering in the source terms of the Navier-Stokes equations is the sum of multiple terms: The gravitational potential entering in the source terms of the Navier-Stokes equations is the sum of multiple terms:
1. ##The potential from the central massive body (primary of mass $`M_*`$): ## The potential from the central massive body (primary of mass $`M_*`$):
$`\Phi_*=-{{ G M_*} \over {r}}`$ $`\Phi_*=-{{ G M_*} \over {r}}`$
2. ##The potential form the planets of mass $m_p$. ## The potential form the planets of mass $m_p$.
