Query: Finite-Difference Multiple Fluid Solution for Source-Driven Rotation in
  Highly Magnetized Linear Plasma Device   The rotation profile of a magnetized plasma cylinder composed of multiple
fluids is investigated analytically, expanding on previous results. The
analytic steady-state solution is used as a benchmark for a time-dependent
multiple-fluid finite-difference code, MITNS: Multiple-Ion Transport Numerical
Solver. Magnetic field evolution is taken into account, both analytically and
numerically. Its details are shown to be of importance when particles are
allowed out of the domain. MITNS reproduces the asymptotic expansion results
for a small parameter $\delta\lll1$. For $\sqrt{m_e/m_i} \sim \delta \ll 1$, a
slightly different regime, dominated by viscosity-induced transport of ions, is
found numerically and analytically. This validation supports the use of this
code for more complex time-dependent calculations in the future.
