class RK3SSP : public Solver

Public Functions

explicit RK3SSP(Options *opt = nullptr)

~RK3SSP() = default

void setMaxTimestep(BoutReal dt) override

inline virtual BoutReal getCurrentTimestep() override

Return the current internal timestep.

virtual int init() override

Initialise the solver.

virtual int run() override

Run the solver, calling monitors nout times, at intervals of tstep. This function is called by solve(), and is specific to each solver type

This should probably be protected, since it shouldn’t be called by users.

Private Functions

void take_step(BoutReal curtime, BoutReal dt, Array<BoutReal> &start, Array<BoutReal> &result)

Take a single step to calculate f1.
