Public Functions

explicit IdaSolver(Options *opts = nullptr)#
~IdaSolver()#
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.

BoutReal run(BoutReal tout)#
void res(BoutReal t, BoutReal *udata, BoutReal *dudata, BoutReal *rdata)#
void pre(BoutReal t, BoutReal cj, BoutReal delta, BoutReal *udata, BoutReal *rvec, BoutReal *zvec)#

Private Members
