Research interests

He is a specialist in the numerical simulations of mechanical engineering problems, in particular, Computational Fluid Dynamics (CFD). In the last ten years he developed a new method called the Particle Finite Element Method (PFEM) to solve fluid mechanics problems including free-surface flow, breaking waves and fragmentation. This method becomes very popular to solve problems like ship and harbour designs, melting of metals, erosion, and polymer combustion or magma analysis. Currently he works on solving CFD problems in Real Time using approximation techniques based on particles and solution of turbulent fluid flows via multi-scale approximations.
