PyCMG is an open source software package for generating virtual concrete mesostructures. Is it implemented in Python. PyCMG allows users to generate a custom concrete mesostructure using a CSV file.

The latest documentation for PyCMG is available at pycmg.readthedocs.org

The features available in the current version of PyCMG are listed below.

• Shape definition using enclosing ellipsoid
• Orientation
• Concavity (depth and width)
• Size

• Specification of an ITZ
• ITZ thickness

Here is a list of publications that use this code. In case you have published a paper using PyCMG, let us know and we can list this here.
