Detailed Description

ChuteWithHopper has a hopper as inflow.

The hopper has two parts as follows to create the finite hopper walls, we take vector between two wall points in xz-plane, then rotate clockwise and make unit length.

Sketch of the hopper

A,B,C denote three points on the left and right hopper walls which are used to construct the hopper. Shift denotes the space by which the chute has to be shifted to the right such that the hopper is in the domain. Note: the wall direction has to be set separately either period of walls.

This creates the hopper on top of the chute, see diagram in class description for details of the points.

Creates the actual hopper and rotates it so as to fit in a geometry in which the chute is parallel to the X-axis.

Todo:
Waarom had ik deze ook al weer gecomment? IFCD: this was probably BvdH
Todo:
Why shift A by arbitrary number of 40, when isHopperCentred_ = True? NB: this is probably the same shift of 40 as happens in HopperInsertionBoundary::generateParticle(RNG) with the calculation of 'point A'. NB2: seems to be just generating a nice 'view' of the hopper (in the center of the viewer...?)

 void ChuteWithHopper::write ( std::ostream & os, bool writeAllParticles = true ) const
overridevirtual

Writes setup properties to an ostream.

Writes object's properties to an ostream

Parameters
 [in] os the ostream [in] writeAllParticles If TRUE, the properties of ALL particles in the particleHandler are written to the ostream. If FALSE, only the properties of the first two particles in the handler are written to the ostream (see DPMBase::write(std::ostream& os, bool writeAllParticles)).

Reimplemented from Chute.
