Explicit Viscosity and Resistivity

Configuration

To introduce explicit viscosity and/or resistivity does not require any special configurations.

Input File

Just set the isotropic viscosity and resistivity (spatial constant) in the problem section non-zero values to switch on the explicit diffusion processes, for example

<problem>
nuiso      = 0.02   # isotropic viscosity
eta_O      = 0.01   # resistivity

will introduce both viscosity and resistivity.
