K-Pattern Simulation

JCrystalSoft, 2012

Version 1.5.1 (12/18/2012)

This software is designed to simulate Kossel patterns and Kikuchi patterns for periodic crystal systems. The program does not perform intensity calculations but reflection conditions for the chosen space group will be observed. This application is a successor to KOQUA, which was a DOS program for the simulation of K-patterns for crystals and quasicrystals.


Main Features

  • Interactive Dragable Plot

  • Stereographic and Gnomonic Projection

  • Reflection Conditions for 230 Space Groups observed

  • Highlight lines with mouse click

  • Save/Load HKL Files (in addition to *.kos files)

  • Angle calculator
