Researchers at Texas A&M University are studying boundary layer stability to gain insight into how transitions from laminar to turbulent flow occur. Their research has applications from low-speed flows in which the laminar-turbulent transition location affects drag and flow separation characteristics to hypersonic flows in which the difference between low laminar and much higher turbulent heating rates can determine whether a space vehicle will successfully pass through the atmosphere or burn up on reentry.
We are anticipating a June release date for Pointwise Version 17.1 R3. Although this is a minor update, it includes several new features in addition to bug fixes. We began the practice of adding new features to minor releases (those that increment the “R” number) after the release of V17.0.

Many aerospace-related applications exist that require surfaces to move within a given region. This can include bodies moving relative to each other, as happens during a store separation, or surfaces actually changing shape, which is what happens with ablation and aeroelasticity.
