◆ placeParticle()

void ChuteInsertionBoundary::placeParticle	(	BaseParticle *	p,
		RNG &	random
	)

overridevirtual

place a particle within the boundary with random radius, position and velocity (within the allowed intervals). Notable properties:

The minimal Z-position is fixedParticleRadius_ (the radius of the particles fixed at the bottom) above the minimal Z-value of the boundary
The particles have an mean velocity of inflowVelocity_ in the X-direction. Furthermore, each particle has a velocity added in all three directions, based on a given inflowVelocityVariance_, which is expressed as a percentage of the inflowVelocity_.
Parameters

[in] random a random number generator

Returns
pointer to the generated particle

Todo:: change to driver level (ask Thomas)
