◆ set_time()

template<int spacedim, class Value >

bool FieldAlgorithmBase< spacedim, Value >::set_time ( const TimeStep & time )

virtual

Set new time value. Some Fields may and some may not implement time dependent values and possibly various types of interpolation. There can not be unified approach to interpolation (at least not on this abstraction level) since some fields (FieldFormula, FieldPython) provides naturally time dependent functions other fields like (FieldConstant, ...), however, can be equipped by various time interpolation schemes. In future, we obviously need time interpolation of higher order so that we can use ODE integrators of higher order.

The method returns true if the value of the field has changed in the new time step.
