## Detailed Description

Used by Chute::createBottom to create an unordered particle layer.

It creates a thick layer of particles in a box of the same x and y dimensions as the Chute, and places a thin slice of that layer as fixed particles at the base of the chute.

 void ChuteBottom::makeRoughBottom ( Chute & chute )

Makes a multilayered rough bottom with thickness thickness_.

Creates a multilayer rough bottom as follows:

1. Sets up a mini simulation, with a horizontal chute and particles poring in on the left (between 0 < Z < inflowHeight_)
2. Runs the simulation for 2000 time steps
3. Removes all particles from the system, EXCEPT those with a Z-position s.t.: hmax = height - maxInflowParticleRadius_; hmax - (thickness_ * maxInflowParticleRadius_) <= Z-position <= hmax
4. Moves all remaining particles to the bottom and fixes them in space
5. Transfers all particles to the Chute argument
Parameters
 [out] chute The Chute object for which the multilayer rough bottom is created
Todo:
Make sure that the post-conditions are:
• N fixed particles in particleHandler, with z-coordinate < 0
• 1 wall, below the rough bottom
• no boundaries
Todo:
IFCD: Only a warning, or an error?

 void ChuteBottom::setupInitialConditions ( )
overridevirtual

Sets up initial conditions before running a chute simulation.

Creates the chute bottom, (periodic or solid) side walls and fills the chute with particles (without using an insertion boundary).

Todo:
The createBottom() function also creates some walls and boundaries, but at slightly different locations. In this version they are removed and reset, but this is (in my opinion (Dinant)) not the correct way.
Todo:
Particles are created without insertion boundary... this reeks of double work (see also Dinant's todo in this same function (ChuteBottom::setupInitialConditions()). (BvdH)
