NumLib::ODESystem< ODESystemTag::FirstOrderImplicitQuasilinear, NonlinearSolverTag::Newton > Class Reference

Detailed Description

Interface for a first-order implicit quasi-linear ODE.

ODEs using this interface also provide a Jacobian in addition to the functionality of the Picard-related interface.
