smod_equil_tc_pinch Submodule

This submodule defines a steady Taylor-Couette flow in a cylindrical geometry where a plasma is confined between two (rotating) coaxial cylinders with an azimuthal magnetic field and constant resistivity.

This equilibrium is taken from Shalybkov, Dima. "Rotational stabilization of pinch instabilities in Taylor-Couette flow.", Physical Review E 75, 047302 (2007).
