Ah, summer holidays, the beach, the sun, brain-matter replaced from thoughts of velocities, pressures and optimizations with pina coladas… Except that I went camping close to a river. Of course, you know what happens when a CFD engineer watches a river for too long? He sees streamlines, algae flowing around bridge pillars in neat flow paths, and immediately spots a leaf following the path of least resistance… and wonders what the residence time of that leaf is. So this all got me thinking about work again. Before I left for my holidays, I was trying to showcase the recirculation zones in our latest invention. Nothing would portray them as badly as I felt they were. I tried vectors, I tried streamlines, I tried scalars and overlaying various field functions on various derived parts. Nothing would do it. I'm not a Colorful Fancy Designer, I'm Dr Mesh and my speciality is meshing, so I really need to learn about these post-processing things. I read with eagerness the posts from Matthew Godo .

Driven by commercial pressure, the design of modern propulsion systems has relied less on traditional model tests and moved to a combination of computational design by analysis methods coupled with systematic validations tests at both model and full scale (Maritime Research). Shown here is a simulation with STAR-CCM+ on a propeller of a state-of-the-art patrol vessel.
