Struphy perturbation

TorusModesSin

Coordinate slices

The sampled perturbation value across the three logical coordinate planes.

XY plane at 0.5

Perturbation value ueta1–eta2 · -9.95e-5 to 9.95e-5

XZ plane at 0.5

Perturbation value ueta1–eta3 · 7.69e-22 to 1.22e-20

YZ plane at 0.5

Perturbation value ueta2–eta3 · -9.98e-5 to 9.98e-5

Coordinate-line profiles

eta1 · other coordinates fixed at 0.5
eta2 · other coordinates fixed at 0.5
eta3 · other coordinates fixed at 0.5

Parameters

ParameterValueDescription
msnullPoloidal mode numbers.

amps[0.0001]Amplitudes of each mode (m_i, n_i).
pfuns["sin"]"sin" or "cos" or "exp" to define the profile functions.
pfun_paramsnull
given_in_basisnullIn which basis the perturbation is represented (see base class).
comp0Which component (0, 1 or 2) of vector is perturbed (=0 for scalar-valued functions)
