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

unsigned n_value=data_pt->nvalue();
Vector<double> time_derivative(n_value);
for (unsigned j=0;j<n_value;j++)
{
for (unsigned t=0;t<ntstorage();t++)
{
time_derivative[j] += data_pt->value(t,j)*weight(i,t);
}
}
cstr elem_len * i
Definition: cfortran.h:603
char t
Definition: cfortran.h:568
unsigned ntstorage() const
Return the number of doubles required to represent history (one for steady)
Definition: timesteppers.h:601
virtual double weight(const unsigned &i, const unsigned &j) const
Access function for j-th weight for the i-th derivative.
Definition: timesteppers.h:594
void time_derivative(const unsigned &i, Data *const &data_pt, Vector< double > &deriv)
Evaluate i-th derivative of all values in Data and return in Vector deriv[].
Definition: timesteppers.h:502

where the time index t is such that

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).
