Detailed Description
////////////////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////////////////
Base class for time-stepping schemes. Timestepper provides an approximation of the temporal derivatives of Data such that the i-th derivative of the j-th value in Data is represented as
where the time index t is such that
t=0refers to the current value of the Datat>0refers to the ‘history’ values, i.e. the doubles that are stored in Data to represent the value's time derivatives. For BDF schemes these doubles are the values at previous times; for other timestepping schemes they can represent quantities such as previous first and second derivatives, etc.
TimeSteppers can evaluate all derivatives up to their order().
The first nprev_values() ‘history values’ represent the values at the previous timesteps. For BDF schemes, nprev_values() = ntstorage()-1 , i.e. all ‘history values’ represent previous values. For Newmark<NSTEPS>, only the first NSTEPS ‘history values’ represent previous values (NSTEPS=1 gives the normal Newmark scheme).
