Advances in FEFLO

This paper summarizes the major improvements and developments that have taken place during the last year for FEFLO, a general-purpose CFD code based on adaptive, unstructured grids. All aspects of a comprehensive CFD capability: gridding, solvers, mesh movement techniques and diagnostics saw important advances, and are treated.
