Grainflow Dynamics, Inc. specializes in modeling the properties of porous and granular materials, and developed discrete-element software to simulate the deformation and flow behavior of particulate assemblies. Grainflow Dynamics' recent work has included utilization of FEM codes to simulate explosions and hypervelocity impacts in geologic media. The firm is currently developing discrete-element simulation models of cohesive lunar regolith for NASA and also utilizing multi-phase flow codes to simulate pneumatic transport of granular solids.
