Data constrained modelling (DCM) refers to a research and development methodology where the sample-specific data and information, and a theoretical model are tightly integrated for quantitative modeling of a physical system .〔http://research.csiro.au/dcm/〕 The DCM methodology has been developed by Dr Y. Sam Yang Et Al at CSIRO since 2007 in relation to 3D characterization of material compositional microstructures and microstructure-based properties, 〔Y. S. Yang, A. Tulloh, I. Cole, S. Furman and A. Hughes, A data-constrained computational model for morphology structures. J. Aust. Ceram. Soc. 43 (2007) 159-164〕 and has been implemented as a DCM software 〔Sam Yang, Andrew Tulloh, Clement Chu, Fiona Chen, John Taylor, DCM - A Software Platform for Advanced 3D Materials Modelling, Characterisation and Visualization. CSIRO Data Access Portal. PID: https://data.csiro.au/dap/landingpage?pid=csiro:9448〕 .〔Sam Yang, Clement Chu, Ben Clennell, A CIPS sandstone X-ray CT data set for DCM tutorial training. CSIRO Data Access Portal. PID: https://data.csiro.au/dap/landingpage?pid=csiro:12663〕 In contrast to the conventional image segmentation technique to derive microstructures from X-ray CT (computed tomography) images which imposes an arbitrary length-scale cut-off at the image pixel size scale, DCM incorporates fine structures below X-ray CT image resolution as voxel compositional partial volumes. Consequently, the fine length-scale information below image pixel size is preserved 〔Y.S.
