class PvodeSolver : public Solver

Public Functions

explicit PvodeSolver(Options *opts = nullptr)

~PvodeSolver()

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.
