olivine LPO simulation

Drex

What is it?

Drex simulates the rotation of crystal orientations and development of preferred orientations in a deforming olivine aggregate.

Motivation

The development of crystal preferred orientations in olivine (and other minerals) has important implications for understanding the dynamics of the earth's interior. Various computer models have been developed to simulate the rotation of crystal orientations in olivine aggregrates, but they have proven difficult to use. This is a version of the popular Drex model, implemented with user-friendliness in mind.

Requirements

Drex requires Matlab 2014 or later. No additional toolboxes are required to run the program.

Installation

No installation is necessary.

Usage

The code does not require input arguments and can be run by calling the program in the MATLAB command window or pushing the green "Run" button. User-adjustable parameters can be found in Drex.m. See the Drex.m file for additional information.

The Latest Version

Details of the latest version can be found on the github project page under server project page under https://github.com/cthissen/Drex-MATLAB

drex-matlab's Issues

some errors i don't konw how to deal with

Hi Christopher,

I am a greenhand to use the matlab,and long for some matlab code for crystallographic orientation especially on HCP material. I am so happy find your code and try to read them.But I encounter a problem about running the code. the errors:

mtex

Hi Christopher,

I just stumbled on this extremely well written peace of code. I like it very much.

Could you imaging to develop you code such that its fits well with the mtex toolbox. Maybe this would increase readability and visibility.

All the best,

Ralf.
