Wired

A highly optimized Biot-Savart Law integrator, written in Julia.

Documentation: https://freestatelabs.github.io/Wired.jl

Installation

This library is not currently part of the Julia language.

Assuming git is already installed on your system:

julia> using Pkg; Pkg.add("github.com/freestatelabs/Wired.jl.git")
julia> using Wired

Basic Usage

Create a Wire of finite length from (x,y,z) = (0,0,0) to (0,0,1000) [m] with 1 kA of current and a finite cross-section radius of 10mm; calculate the magnetic flux density along the x-axis and plot:

using Plots, Wired

wire = Wire([0,0,0], [0,0,1000], 1000, 0.010);
line = Line([0,0,0], [0.1,0,0], 1000);	# N=1000 points
B = bfield(line.nodes, [wire]);

plot(line.nodes[:,1], B[:,2], label="By")
xlabel!("Distance from Origin Along X-Axis [m]")
ylabel!("Magnetic Flux Density (By) [T]")

Output:

Features

Fast, efficient Biot-Savart Law integration - magnetostatic calculation of magnetic flux density generated by time-invariant currents flowing through filamentized geometries:

• Finite length wires with finite and infinitesimal circular cross-sections
• Circular rings with finite and infinitesimal circular cross-sections
• Load/save functionality
• Use finite element meshes as current-carrying sources
• Calculate Lorentz body-forces on finite element meshes
• Field primitives: lines
• Parallel/multi-threaded processing using Julia's Threads module

In Development

• Parallel processing on GPU using CUDA
• Field primitives: planes
• Further speed improvements using Polyester.jl and/or LoopVectorization.jl
