The Centre for Scientific Computing

 

Hrvoje Jasak has a first degree in mechanical engineering from the University of Zagreb (1992), and a PhD in CFD from Imperial College London, with Prof. A.D. Gosman (1993-1996). He was a Senior Development Engineer at CD-adapco (now Siemens PLM) (1996-2000), Technical Director at Nabla Ltd (2000-2006), and has worked on new generation software at Ansys-Fluent Inc. (2000-2008).

Hrvoje holds a Professorship at the University of Zagreb and a Mercator Fellowship at TU Darmstadt, Germany.
Hrvoje is one of the two original co-authors of OpenFOAM, Chair of the OpenFOAM Numerics Technical Committee and a member of OpenFOAM Governance Steering Committee.

His research interests are on numerical simulation methods, mathematical modelling of continuum phenomena and numerical mathematics, numerical modelling in multi-phase and free surface flows, naval hydrodynamics and wave modelling, dynamic mesh handling, error estimation, mesh adaptivity and practical software development. He is particularly experienced in numerical modelling of complex heat and mass transfer systems and multi-physics applications.
Hrvoje is a professional programmer with 25 years of experience in C++ and object-oriented software design, high performance computing, linear algebra on HPC platforms and related topics. In his career he has managed large software projects and wrote approx. 1 million lines of C++ source code.
