Kinetic model
Vlasov
Vlasov equation for a single species in a static background magnetic field.
Overview
Vlasov is the simplest kinetic test-particle model in the 6D hierarchy.
It evolves particles in a static magnetic background without electric or magnetic self-consistency.
Use cases
This model is appropriate for:
- test-particle motion in prescribed magnetic fields
- verification of the Boris-like VxB and PushEta splitting
- reduced kinetic transport studies without field feedback
Governing equations

Example
Create and initialize a Vlasov test-particle model:
from struphy.models import Vlasov
model = Vlasov()
