Personal profile
Profile
Working since 1991 with development, implementation and
application of computational fluid
dynamics, with the main focus on flows related to wind turbines and
flow over complex terrain.
This work has been centered around a role as one of two main
developers of the EllipSys2D/3D
Navier-Stokes solvers. The work has been comprehensive, covering
the basic implementation
and algorithm development, optimization and verification of the
actual flow solvers for several
computer architectures, code parallelization, turbulence modeling,
transition modeling, hyperbolic
mesh generation, and moving grid algorithms.
