Multi-scale Computation and Computational Mechanics
Researchers at Michigan are using multi-scale computational methods to research ranging from the molecular basis of soot formation in combustion to the manner in which molecular-level defects affect macroscopic mechanical properties (see below). These methods focus on predicting the mechanical, electrical, and optical behavior of materials and structures from smaller scale models in an accurate and reliable way. Such scale-bridging sometimes involves the inclusion of quantum-mechanical calculations or complex substructure models.
Computational mechanics seeks to develop new methods for computer aided prediction of physical phenomenon important to engineering, whether it be how to design the microscale of a structure to optimize its wave propagation response or predicting DNA conformations.
We leverage the resources of the parallel computing cluster maintained by the Michigan Center for Advanced Computing to perform large scale computations. (View Affiliated Researchers)
