Kinetic background
Maxwellian3D
A
struphy.kinetic_background.base.Maxwellian depending
and on three () Cartesian velocities.
Phase space
- Velocity dimension
- 3

Velocity-space distribution
f₀ over (vx, vy), remaining velocity axes integrated out, at logical position η = (0.5, 0.5, 0.5).
- vx
- -5 to 5
- vy
- -5 to 5
Reduced profiles
The distribution along each velocity axis, with every other phase-space axis integrated out.
Parameters
Constructor defaults. Moments are given as a background value (a float or a callable) paired with an optional perturbation.
| Parameter | Default | Perturbation | Description |
|---|---|---|---|
n | 1 | None | Moments of the Maxwellian as tuples. The first entry defines the background (float for constant background or callable), the second entry defines a Perturbation (can be None). |
u1 | 0 | None | — |
u2 | 0 | None | — |
u3 | 0 | None | — |
vth1 | 1 | None | — |
vth2 | 1 | None | — |
vth3 | 1 | None | — |
uniform_on_disc | false | — | Whether the density n is uniform on the disc. |
