Detailed Description

template<size_t VolumeDim>
class dg::Events::ObserveTimeStepVolume< VolumeDim >

Observe the time step in the volume.

Observe the time step size in each element. Each element is output as a single cell with two points per dimension and the observation constant on all those points.

Writes volume quantities:

  • InertialCoordinates (only element corners)
  • Time step
  • Slab fraction
  • Minimum grid spacing

◆ needs_evolved_variables()

template<size_t VolumeDim>
bool dg::Events::ObserveTimeStepVolume< VolumeDim >::needs_evolved_variables ( ) const
overridevirtual

Whether the event uses anything depending on the evolved_variables. If this returns false, anything depending on the evolved variables may have an incorrect value when the event is run.

Implements Event.
