Gretar Tryggvason is the Viola D. Hank Professor of Aerospace and Mechanical Engineering Department at the University of Notre Dame. He is known for developing a front tracking method to simulate multiphase flows and free surface flows. Tryggvason is the Editor-in-Chief of Journal of Computational Physics.[1]

Area of research[edit]

Tryggvason has been a leading worker computational fluid dynamics and numerical methods. He is well known for his research on numerical simulations of vortex flows, multiphase flows, free surface flows, and flows with phase changes. For simulating multiphase flows, he and his co-workers have developed a front tracking method that incorporates an unstructured, moving grid within an underlying Eulerian grid.[2][3]
