CoeffDiffusionLin
Generic linear diffusion term (Values are NOT in logarithmic form), where the Jacobian is computed using forward automatic differentiation.
Overview
CoeffDiffusionLin is the diffusion term used for variables not in logarithmic form.
The strong form for CoeffDiffusionLin is defined as
Where is the diffusion component of a species' flux, is the diffusion coefficient, is the density, and is the scaling factor of the mesh. In the case for the electrostatic approximation, is replaced with the potential and is replaced with the permittivity of free space.
Example Input File Syntax
An example of how to use CoeffDiffusionLin can be found in the test file Lymberopoulos_with_argon_metastables.i.

# Two charged particle species are considered, creatively named 'pos'
# and 'neg'. They both have the same initial conditions and boundary
# conditions; the only difference is their charge.
# As the voltage varies, the particle flux to the right boundary
# (including both advection and diffusion) will switch polarity and
# the surface charge will become increasingly negative or positive.
#
# The left boundary is a driven electrode with a sinusoidal waveform.
# A dielectric boundary condition including surface charge accumulation
# is included on the right boundary.
#
# Note that without surface charge the electric field across both
# boundaries should be identical since their permittivities are

# Surface charge shields the electric field in the gas region,
