Several new significant features have been added in our latest version, Pointwise V18.4. In this Q&A, our Product Planning Team will answer questions about the new features, the future of computational fluid dynamics (CFD), and the Pointwise development plan.
Read the case study, "Hybrid Meshing Key to Improving CFD Simulation Efficiency," which summarizes how a T-Rex hybrid grid showed up to a seven-fold improvement in solution efficiency compared to other approaches in predicting thrust and torque for a marine propeller.
This webinar covering newly released features is your guide to the latest offerings in Pointwise. This quick overview demonstrates the new features so that you will know how to use and where to quickly find these features.
Watch this on-demand webinar that will help you determine the best type of mesh to use for the fastest and most accurate CFD simulations.
Students at KTH Royal Institute of Technology in Sweden investigated the performance of a pick-and-place machine using CFD. Pointwise was used to perform a grid refinement study for a static simulation where the nozzle of the machine as well as the distance to the component varied. Additionally, an overset mesh was generated for a 1-DOF dynamic simulation.
Pointwise is supporting two AIAA workshops (the 3rd High Lift Prediction and the 1st Geometry and Mesh Generation Workshop) to be held prior to AIAA Aviation in June 2017. We generated several type of meshes (unstructured, hybrid, hybrid overset, and high order) for the NASA High Lift Common Research Model that are described here.
Researchers at Pennsylvania State University’s Applied Research Laboratory share an overview of their ongoing work involving overset grid CFD simulations of an incompressible rotorcraft hub they performed using the overset meshing tools available in Pointwise.
This video demonstrates the process of generating overlapping grids, setting up and executing Suggar++, and exporting the domain connectivity information all from within Pointwise. We demonstrate an overset flow simulation using the Caelus CFD solver.
Researchers at The Pennsylvania State University used the overset grid assembly tools in Pointwise to generate high-quality structured overset meshes for analysis of a horizontal axis water turbine. The flexibility offered by overset grids made it easy for them to add higher resolution grid blocks to resolve regions with high flow gradients like the turbine blade tips, wakes and tip vortices. This resulted in good agreement with experimental data even for flow details like the interaction between blade wakes and the support tower.
As part of their capstone senior project, engineering students at Technion – Israel Institute of Technology used Pointwise to assist in the detailed aerodynamic design of a highly-maneuverable, supersonic missile they designed.
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.
