3D Cylinder Crystalline Structure: The generation of three-dimensional (3D) microstructures with multiple constituents is an important part of multiscale computational simulation and design. Realistic 3D microstructures for multiphase materials are difficult to obtain experimentally or computationally. The left CT scan of sucrose grains, which are a useful stand in for many energetic materials, on the right the images have been resolved into 3D objects through a process called morphological image processing. Now individual constituents can clearly be seen, allowing for further analysis and use in computational studies. Contributors: Daniel Olsen Yaochi Wei, Karla Wagner, Naresh Thadhani, and Min Zhou
