What it solves

For each marker

p

, solves

\frac{d v _{p} ( t )}{d t} = \frac{1}{ε} v_{p} (t) \times (B + B_{add}),

where $ε = 1/ (Ω^_{c} t^)$ is a constant scaling factor, and for rotation vector $B$ and optional, additional fixed rotation vector $B_{add}$ , both given as a 2-form:

B = \frac{D F B ^ ^{2}}{g} .

Available algorithms:

analytic
implicit.

The variables this step updates over a time step dt, and the discrete spaces each one accepts.
