DSMC.Particles

Particles, ensembles, flow parameters.

Particles

type Particle = (Point, Vec3)

Gas particle with position and velocity.

move :: Time -> Particle -> Particle

Linearly move particle for t time and update its position.

Particle ensembles

type Ensemble = Array U DIM1 Particle

Repa array of particles.

emptyEnsemble :: Ensemble

Ensemble with zero particles in it.

ensembleSize :: Ensemble -> Int

Amount of particles in an ensemble.

filterEnsemble :: (Particle -> Bool) -> Ensemble -> Ensemble

Filter out those particles which do not satisfy the predicate.

printEnsemble :: Ensemble -> IO ()

Print particles, one per row, using the format:

 x y z u v w

where x y z are position coordinates and u v w are velocity components. This is handy for debugging purposes.

Flows

data Flow

Flow with given concentration, temperature, mass of molecule and macroscopic velocity.

Constructors

Fields

concentration :: !Double

temperature :: !Double

mass :: !Double

velocity :: !Vec3

statWeight :: !Double

How many real particles a single simulator represents.

Instances

Show Flow

modelConcentration :: Flow -> Double

Calculate model concentration to simulate real flow concentration wrt statistical weight of single particle as set in flow options.
