Research Interests

Overset Grids

Eliminating the gridding bottleneck by isolating individual bodies onto overlapping grids. Simplifying the gridding process and making automated gridding tractable by reducing geometric complexity of each component grid. High order, shock preserving interpolation methods transfer field variables between each component grid while coupling or monolithic matrix manipulation ensures reliable convergence to the correct solution.

Overset Grid Example
Parallel computing architecture

High Performance Computing

Solving bigger problems, faster than ever before. Bringing high-fidelity computations into the design space by optimizing software to leverage the latest architectures and libraries. Automating massively parallel, high performance computing to simplify the end user's workflow, providing better and more meaningful results.

Fluid-Structure Interaction

Blurring the boundary between structural and fluid dynamics with coupled or monolithic solvers. Adaptive grid refinement, automated mesh deformation, and moving overset grids enables the structural dynamics to respond instantaneously with the fluid forces. From alternative energy sources to advanced bio-inspired flying machines, harnessing the interaction between solid and fluid dynamics opens up new design possibilities.
