This submodule defines a cylindrical equilibrium in which a Suydam surface is present, such that this gives rises to Suydam cluster modes. The geometry can be overriden using the parfile.
This equilibrium is taken from Nijboer, R. J., Holst, B., Poedts, S., & Goedbloed, J. P. (1997). Calculating magnetohydrodynamic flow spectra. Computer physics communications, 106(1-2), 39-52.
Default values are given by
and can all be changed in the parfile.
