Meshing for Control, Quality, and Automation
You can generate structured multi-block, unstructured, hybrid, and overset meshes for viscous simulations with precise control over point placement and clustering to get the resolution you need. At the same time, Pointwise’s core meshing methods produce cells of high quality to ensure convergence and accuracy in your CFD solution.
Using Pointwise’s Glyph scripting language, you can automate most or all of the mesh generation process by writing macros and templates. And the software’s plug-in SDK gives you the ability to write a mesh exporter customized to your CFD solver. Between Glyph and plug-ins, you can customize the entire meshing process from geometry model import to flow solver export.
Numerical Investigation of a Pick-and-Place Machine
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.
Mesh Generation for the NASA HL-CRM
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.
Rotorcraft Hub Wake Analysis Using Overset Meshes
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. Preliminary CFD results show good agreement with empirical rotor hub wake measurements. Pointwise has become an integral part of these researchers' toolset as they continue their investigations into important flow phenomena for their sponsors in the rotorcraft industry.
High Fidelity Overset Structured Mesh Generation for Marine Hydrokinetic Devices
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.
Overset Tools and Other New Features in Pointwise V17.3
Join us as we demonstrate and discuss the new features available in Pointwise Version 17.3. You will learn about the new overset grid assembly tools and other new features like the Examine in Solve command. This webinar will demonstrate how you can make your meshing experience much more efficient using all the new tools in this latest release of the software.
Texas A&M Uses Pointwise Meshes for Boundary Layer Stability Analysis
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.
