Detailed Description

Cylindrical source for density diffusion in the MHD model.

Refer to DensityDiffusionFlux for details on the calculation of the diffusion coefficient.

Density diffusion in cartesian coordinates

\[ \frac{\partial \rho}{\partial t} + \nabla \cdot (-D \nabla \rho) = 0 \]

becomes in cylindrical coordinates

\[ \frac{\partial \rho}{ \partial t} + \nabla_{cart} (-D \nabla \rho) = D \nabla_r(\rho) / r \]

where \(\nabla_{cart} \cdot\) is the cartesian divergence operator and \(\nabla_r \) is the radial gradient operator.
