Detailed Description

Base class ODE Solver (under construction).

ODE solved in this simulation U_t = L_delta(U) (1) where L_delta is the spatial discretization operator. Semi-discrete equation (Method of Line MOL). Spatial and time discretization are done separately.

Time-Stepping is a two-steps integrator that belongs to Runge-Kutta family.
