Member Function Documentation

◆ eval_rhs()

void wxm::temporal::implicit::eval_rhs ( int rk_stage )

◆ setup()

void wxm::temporal::implicit::setup ( const WxCryptSet & wxc )

overridevirtual

Setup object using supplied crypset.

This method should read in parameters needed to initialize it. May only be called once.

Parameters

wxc	Cryptset using which the object is set up.

Reimplemented from WxObject.

◆ step()

WxStepperStatus wxm::temporal::implicit::step ( )

overridevirtual

Advance the stepper by assigned time step.

The status of the step should be encoded in the return object. See WxStepperStatus for details on what fields can be set.

Returns: Status of stepper

Implements WxStepper.
