The DCM software is a Microsoft Windows™-based application for 3D microstructure characterization, modelling and visualization. It include the following functionalities:
• Generate digital 3D represen... moretation of material compositional phases in a sample using the data-constrained modelling methodology and X-ray CT data, even for the cases that there are partial volumes of multiple phases in the same image voxel;
• Visual presentation of 3D volumetric data. The visualization is compatible with various display devices, including stereo 3D monitors;
• Exporting 3D data in various formats, including the web-friendly Web3D format for interactive 3D online view, animation, serial sectional slices, etc.;
• Functionality of the software can be extended by adding plug-in modules to perform virtually unlimited 3D modelling. A set of C++ programming API is included for user convenience.
The DcmLite can be downloaded for evaluation. Please feel free to contact us if you would be interested in acquiring a DCM software user licence, R&D collaboration, commercial exploitation, or knowing more about DCM. The DCM website is at http://research.csiro.au/dcm.

It has been used to simu... morelate flow and determine permeability of two real-world rock samples as published by Li et al (2014) in PHYSICAL REVIEW E 90, 033301 (2014);Journal of Shanxi University(Nat.Sci.Ed.) 38(2):289-297,2015;10th International Conference on CFD in Oil & Gas, Metallurgical and Process Industries,SINTEF, Trondheim, Norway,17-19 June 2014.
The effective percolating fractions of voxels were estimated using the DCM software (Yang et al, CSIRO Data-Access Portal - https://data.csiro.au/dap/landingpage?pid=csiro:9448) generated volume fractions. More information about DCM is available at http://research.csiro.au/dcm/ and https://en.wikipedia.org/wiki/Data_constrained_modelling.
- The plugin requires voxel-based percolation fraction, plus other parameters as the following:
+ Effective percolation fraction channel index
+ Fluid speed channel index
+ Maximum iterations for computation
+ Display interval
+ Voxel physical size in microns
- The plugin can estimate the effective percolation fraction using void and calcite volume fractions as detailed in above quoted papers. The input parameters are the following:
+ Void volume fraction channel index
+ Calcite volume fractions channel index
+ Fluid speed channel index
+ Maximum iterations for computation
+ Display interval
+ Volume fraction of Calcite
+ Voxel physical size in microns
