Generic Parameters

module Config

export TimeProperties

using ..BoundaryTrait
using ..Vectors

using ..Boxes: Box, axes
export Box, axes

using Unitful
using Unitful.DefaultSymbols
using ..CarboKitten: TimeProperties

<<config-types>>

end

Physical parameters of CarboKitten all should have units, see our refresher on Unitful.jl.

Time properties

Time stepping is specified in TimeProperties. We'll have time_steps number of time steps, each of physical time Δt. However, only one in write_interval steps is written to disk.

Vectors

To trace the position of particles we define a NamedTuple with x and y members and define common vector operations on those.

module Vectors

export Vec2

Vec2 = @NamedTuple{x::Float64, y::Float64}
Base.:+(a::Vec2, b::Vec2) = (x=a.x+b.x, y=a.y+b.y)
Base.abs2(a::Vec2) = a.x^2 + a.y^2
Base.abs(a::Vec2) = √(abs2(a))
Base.:*(a::Vec2, b::Float64) = (x=a.x*b, y=a.y*b)
Base.:/(a::Vec2, b::Float64) = (x=a.x/b, y=a.y/b)
Base.:*(a::Float64, b::Vec2) = b*a
Base.:-(a::Vec2, b::Vec2) = (x=a.x-b.x, y=a.y-b.y)
Base.:-(a::Vec2) = (x=-a.x, y=-a.y)
Base.zero(::Type{Vec2}) = (x=0.0, y=0.0)
