Detailed Description

Computes total angular momentum of all SPH particles with a respect to the reference frame.

Storage must contain at least particle masses and particle positions with velocities, checked by assert. If the particles also have nonzero angular velocities, the 'local' angular momenta are added to the total angular momentum.

Member Function Documentation

◆ evaluate()

Vector TotalAngularMomentum::evaluate ( const Storage & storage ) const

overridevirtual

Computes the integral quantity using particles in the storage.

Storage must contain quantites relevant to the integral implementation. Generally positions, masses and density must be present.

Todo:: consolidate the angular momentum here - always in local frame? introduce physical quantity?

Implements IIntegral< Vector >.

◆ getName()

virtual std::string TotalAngularMomentum::getName ( ) const

inlineoverridevirtual

Returns the name of the integral.

Needed to label the integral in logs, GUI etc.
