Projects

Project Chrono

    Chrono is a suite of open-source softwares for the investigation of MBD problems. I have been one of the main developers of Chrono and the lead developer of Chrono::FSI, an open-source software for the simulation of the fluid-solid interaction problems involving larger domain deformation and free surface flow. Chrono has been used in projects offered by US Army TARDEC, Oshkosh Truck, NASA, Caterpillar, MSC Software, and Statoil.

GPUSPH_Chrono Integration

    GPUSPH is an open-source CUDA implementation of the weakly-compressible Smoothed Particle Hydrodynamics (SPH), which is developed by several contributors from US and Europe. Relying on my background on SPH and Chrono, I helped adding Chrono functionality for multibody dynamics into GPUSPH to provide a framework for the simulation of fluid-solid interaction problems. The changes will appear in the next release of the code.

Miscellaneous Open Source Codes
