This report is the result of a workshop on Computational Fluid Dynamics, held at FOI Ursvik, 2001-10-30 with participation from Computational Aerodynamics at the Aeronautics Division and Computational Physics at the Weapons & Protection Division. The workshop indicates that FOI is active in a very wide range of activities within the field of Computational Fluid Dynamics, ranging from basic research on numerical methods and turbulence to real-world problem solving relevant to the Swedish defence and the Swedish defence industry. The current state-of-the-art at FOI holds strong promises for the future, and synergistic effects can be achieved by collaboration in new projects utilizing the respective competences of the two groups.
