Detailed Description

Defines the non-averaged directions on which spatial coarse-graining is applied (the x-direction for X); all other directions are averaged
over homogeneously.

See XYZ for details.

Member Function Documentation

getCNormal()

Mdouble X::getCNormal	(	const BaseInteraction &	c,
		const Vec3D &	normal
	)		const

For the Interaction between particles/walls P and I, this function returns the dot product between the normal vector of the interaction and the branch vector from the current CGPoint towards the contact point.

{
    return (c.getContactPoint().X - x_) * normal.X;
}

References calibrate::c, WallFunction::normal(), and x_.

getDistanceSquared()

Mdouble X::getDistanceSquared

(

const Vec3D &

p

)

const

Returns the square of the distance between the particle p and the current CGPoint, in the non-averaged directions.

{
    return mathsFunc::square(p.X - x_);
}

getINormal()

Mdouble X::getINormal	(	const BaseInteraction &	c,
		const Vec3D &	normal
	)		const

For the Interaction between particles/walls P and I, this function returns the dot product between the normal vector of the interaction and the branch vector from the current CGPoint towards I.

Todo:

change from normal.X to sign(normal.X)

{
