were selected to generate sausage magnetoacoustic waves. The waveguide halfwidths is optional in both waveguides (dense slab and current sheet).

We perturbed the initial equilibrium by the Gaussian pulse in the Y component of the velocity. The perturbation point in waveguide as well as time of perturbation are optional.

Initial amplitude of the pulse and the half-widths of the velocity pulse in the X and Y directions are also optional.
