Detailed Description

template<typename ControlSystems>
class control_system::BNSEvent< ControlSystems >

An Event that computes the center of mass for \(x > 0\) and \(x < 0\) where \(x\) is the in the Frame::Grid.

Details

See control_system::measurements::center_of_mass_integral_on_element for the calculation of the CoM. This event then does a reduction and calls control_system::PostReductionSendBNSStarCentersToControlSystem as a post reduction callback.

Template Parameters
ControlSystemstmpl::list of all control systems that use this event.

◆ needs_evolved_variables()

template<typename ControlSystems >
bool control_system::BNSEvent< ControlSystems >::needs_evolved_variables ( ) const
inlineoverridevirtual

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.
