# TSDISCGRAD

ODE solver using the discrete gradients version of the implicit midpoint method

Notes: This is the implicit midpoint rule, with an optional term that guarantees the discrete gradient property. This timestepper applies to systems of the form

    u_t = S(u) grad F(u)

where S(u) is a linear operator, and F is a functional of u.
