or computer-generated materials are designed to capture
the essential attributes of their real counterparts.
However, computer simulation removes the constraints of
the laboratory. This means that pore structure can be
quickly and easily varied (and pushed to new limits) as a
means to better understand its impact on bulk properties.
A number different algorithms are being used to generate
computer-simulated materials. The one that is best suited
for a given application depends strongly on the particular
microstructure of the material. What is then done with the virtual
material depends on the project goals. Collaborators in
the area of mechanics are using models of particulate
materials directly. Our emphasis is on structure and
transport, which means the computer-generated materials
serve as highly characterized domains for studying
morphology or performing flow modeling.
