McXtrace: Polycrystal Component

[ Identification | Description | Input parameters | Output parameters | Links ]

The Polycrystal Component

Based on code by: Erik Knudsen, Kenichi Oikawa, and Alberto Cereser Polycrystal made from single crystal-like voxels

Identification

  • Author: Martin Cramer Pedersen (mcpe@nbi.dk)
  • Origin: University of Copenhagen
  • Date: January 2015
  • Version:(Unknown)

Description

The component creates a three-dimensional grid of cubic instances of the Single_crystal-component,through
which the rays are propagated. The component relies on a list of possible orientations and stretches of the
initial unit cell and a list correlating each voxel of the polycrystal to an entry in the list of rotations
and stretches.

Input parameters

Parameters in boldface are required; the others are optional.
