class CvodeSolver : public Solver

Public Functions

CvodeSolver(Options *opts = nullptr)
void setJacobian(Jacobian j)

Specify a Jacobian (optional)

BoutReal getCurrentTimestep()

Return the current internal timestep.

int init(int nout, BoutReal tstep)

Initialise the solver NOTE: nout and tstep should be passed to run, not init. Needed because of how the PETSc TS code works

int run()

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.

BoutReal run(BoutReal tout)
void resetInternalFields()

Should wipe out internal field vector and reset from current field object data.

void rhs(BoutReal t, BoutReal *udata, BoutReal *dudata)
void pre(BoutReal t, BoutReal gamma, BoutReal delta, BoutReal *udata, BoutReal *rvec, BoutReal *zvec)
void jac(BoutReal t, BoutReal *ydata, BoutReal *vdata, BoutReal *Jvdata)

Private Functions

void set_abstol_values(BoutReal *abstolvec_data, std::vector<BoutReal> &f2dtols, std::vector<BoutReal> &f3dtols)
void loop_abstol_values_op(Ind2D i2d, BoutReal *abstolvec_data, int &p, std::vector<BoutReal> &f2dtols, std::vector<BoutReal> &f3dtols, bool bndry)
