Particle velocity space

A struct vSpace <: AbstractSetup defines the particle velocity setup of a simulation. Structs for 1-3 dimensional particle velocity space are built. Note that these structs work for both single-component and multi-component substances.

It contains

  • u0 (v0, w0): location of starting point
  • u1 (v1, w1): location of ending point
  • nu (nv, nw): number of cells in one direction
  • u (v, w): locations of middle points of all cells
  • du (dv, dw): intervals of all cell points
  • weights: quadrature weights for numerical integral

Note that the one-dimensional velocity space can be used to handle 1-3 dimensional unstructured topology as well.

For the simulation cases where no phase-space evolution is involved, vSpace can be set as nothing directly.

vSpace = nothing
