Faster coupled calculated with Lerche / Newberger rules

Previously tensors for coupled distribution functions were calculated by summing over cyclotron harmonics until convergence was reached. The Lerche / Newberger trick reduces the infinite sum into just one 2D integral. Note the trick couples the parallel and perpendicular integrals.

Can also pass wavenumber components as DualNumbers

Fix perf bug for numerical parallel integrals

The configured tolerance wasn't getting passed through.

Faster converger and a slowing down

What's Changed

• faster convergeruse

• ability to use Duals on perp wavenumbers

• slowing down distribution

• #7

Full Changelog: 0.1.5...0.1.6

0.1.5

Properly define conductivity tensors.

Expose limits on distribution functions

The lower and upper limits on distribution function velocity support has been exposed.
Also:

• fix allocations for bitreverser
• catch code path in test for coupled distribution functions

What's Changed

• Nextfixes by @jwscook in #5

Full Changelog: 0.1.3...0.1.4

integrand cutoff for coupled species to account for heaviside function

The integrand in speed and pitch angle for coupled distribution functions is cutoff at the upper speed to mimic Heaviside function cutoffs in the distribution function.

Allow plasma structs to hold tuples as well as abstract vectors

Before plasmas had to consist of AbstractVectors of species but now it can contain a Tuple of species.

What's Changed

• Plasma struct container is restricted to AbstractVector - allow Tuples by @jwscook in #3

Full Changelog: 0.1.1...0.1.2

zero k-parallel coupled distribution function bugfix

Bug fix for zero parallel wavenumber and coupled distribution functions.

Initial Release
