Cassonflow: A verified open-source solver for MHD Casson-fluid flow over a nonlinear stretching sheet in a porous medium

Open-source Python package that solves the similarity boundary-value problem for MHD Casson-fluid flow over a nonlinearly stretching sheet in a porous medium. It provides Newton shooting (Runge-Kutta with exact variational Jacobian) and fourth-order collocation solvers, an asymptotic far-field condition, automatic domain-independence verification, detection of non-monotone solution branches, continuation sweeps, a command-line interface and a test suite.
