Physical models

Summary

Package: dynamodels — physical models live in dynamodels.physical and are re-exported as romda.models.physical. All use IVPIntegrator (scipy.integrate.solve_ivp) except KS, which uses a discrete ETDRK4 map.

Governing equations, figures and quickstart examples for each model are on the dynamodels docs site — follow the links below.
