Struct GravitySource 

pub struct GravitySource<T, D>
where
    T: Scalar,
    D: SmallDim,
    DefaultAllocator: DimAllocator<T, D>,
{ /* private fields */ }

A source for the gravitational force.

This source implements the force density

$$ \rho \vec g, $$

where $\rho: \Omega \rightarrow \mathbb{R}_{\geq 0}$ is a density function and $\vec g \in \mathbb{R}^d$ is the $d$-dimensional graviational acceleration vector.

In conjunction with ElementSourceAssembler, the source corresponds to the weak form term

$$ \int_\Omega \rho \vec g \, : \, \vec w \, \d{\vec X}, $$

where $\vec w: \Omega \rightarrow \mathbb{R}^d$ is a test function.
