About the lab 

The Computational Engineering Physics Laboratory at Western Michigan University (WMU) engages in computational research in multidisciplinary engineering physics. Funding from various government and private industries support graduate students who perform fundamental and applied research of ground and flight vehicles. Project research covers fluid dynamics, heat transfer, fluid/structure interactions, mechanics, and biomedical fields. Research needs have prompted the development of computational tools in-house, such as Navier-Stokes equations solvers, Burnett equations solver, direct simulation Monte Carlo solvers. Commercially available solvers and open-source solvers, including FLUENT, ICEM/CFD, ANSYS, ABAQUS, ADAMS, OpenFoam, and SPARTA have also been successfully applied.
