Detailed Description

template<unsigned DIM>
class ImmersedBoundaryKinematicFeedbackForce< DIM >

A force class for use in immersed boundary simulations. This force implements kinematic feedback; amplification of relative motion of cells sliding past one another.

◆ AddImmersedBoundaryForceContribution()

template<unsigned DIM>

void ImmersedBoundaryKinematicFeedbackForce< DIM >::AddImmersedBoundaryForceContribution	(	std::vector< std::pair< Node< DIM > , Node< DIM > > > &	rNodePairs,
		ImmersedBoundaryCellPopulation< DIM > &	rCellPopulation
	)

virtual

Overridden AddImmersedBoundaryForceContribution() method. Calculates the force on each node in the immersed boundary cell population as a result of kinematic feedback.

Parameters

rNodePairs	reference to a vector set of node pairs between which to contribute the force
rCellPopulation	reference to the cell population

Implements AbstractImmersedBoundaryForce< DIM >.

◆ CalculateRelativeVelocityComponent()

template<unsigned DIM>

double ImmersedBoundaryKinematicFeedbackForce< DIM >::CalculateRelativeVelocityComponent	(	const c_vector< double, DIM > &	rPreviousDisp,
		const c_vector< double, DIM > &	rCurrentDisp,
		c_vector< double, DIM > &	rUnitPerp
	)

private

Helper function for AddImmersedBoundaryForceContribution(). Calculates the component of their relative velocity in the direction perpendicular to the line joining the two nodes at the previous time step.

This relative velocity is a measure of shear between two boundaries, which this force class amplifies.

Parameters

rPreviousDisp	displacement between a pair of interacting nodes at the previous time step
rCurrentDisp	displacement between the same pair of interacting nodes at the current time step
rUnitPerp	filled in as a unit vector perpendicular to previousDisp
