       AbsGrainGen

Grain generator which can be used in conjunction with the GougeConfigPrms and GrainRandomBoxPacker classes. Generates grains which consist of a particles packed into a circle/sphere. Spherical particle radii are generated independent of grain size.

Instance Methods

[hide private]

__init__(self, minGRadius, maxGRadius, do2d=False, minPRadius=None, maxPRadius=None, maxInsertFails=5000)
Initialise the generator.

Grain

getGrain(self, p)
Uses RandomSpherePacker to create a grain consisting of randomly sized particles packed into a sphere with centre p.getPosn() and radius p.getRadius().

Method Details

[hide private]

init(self, minGRadius, maxGRadius, do2d=False, minPRadius=None, maxPRadius=None, maxInsertFails=5000)
(Constructor)

Initialise the generator.

Parameters:

minGRadius (float) - minimum grain radius
maxGRadius (float) - maximum grain radius
do2d (bool) - If True, grain particles all occur on the z=0 plane (ie particles packed into a circle).
minPRadius (float) - The minimum radius of randomly generated particles.
maxPRadius (float) - The maximum radius of randomly generated particles.

getGrain(self, p)

Uses RandomSpherePacker to create a grain consisting of randomly sized particles packed into a sphere with centre p.getPosn() and radius p.getRadius(). The random particle radii will lie in the range (self.minPRadius,self.maxPRadius)

Parameters:

p (SimpleSphere) - p.getPosn() and p.getRadius() determine the size and position of the returned grain.

Returns: Grain

A spherical grain of randomly sized particles.
