Struphy perturbation

Erf_z

Coordinate slices

The sampled perturbation value across the three logical coordinate planes.

Perturbation value ueta1–eta2 · 0.00e+0 to 0.00e+0

Perturbation value ueta1–eta3 · -1.00e-4 to 1.00e-4

Perturbation value ueta2–eta3 · -1.00e-4 to 1.00e-4

eta1 · other coordinates fixed at 0.5

eta2 · other coordinates fixed at 0.5

eta3 · other coordinates fixed at 0.5

Parameter	Value	Description
`amp`	`0.0001`	Amplitude of the velocity on each side.
`delta`	`0.06666666666666667`	Characteristic size of the shear layer
`given_in_basis`	`null`	In which basis the perturbation is represented (see base class).
`comp`	`0`	Which component (0, 1 or 2) of vector is perturbed (=0 for scalar-valued functions)
