Meshing Solutions for the Marine Industry

Marine and hydrodynamic applications of CFD are a field where Pointwise's meshing software has a long history. From racing yachts to cargo ships to submarines, from appendage drag to surface wave capturing to hydroacoustics, Pointwise supports the accurate meshing required.

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.

Big Wave Surfboard Optimization Using Pointwise and CRUNCH CFD

Big Wave Surfboard Optimization Using Pointwise and CRUNCH CFD

Working with one of the world's top big wave board shapers, engineers at CRAFT Tech have applied computational fluid dynamics (CFD) within a design optimization process, employing a genetic algorithm to evolve the design of a big wave surfboard. In this article, we will explore the design framework that allowed over 100 design iterations to be explored, resulting in a higher speed, lower drag, big wave surfboard design.

High Fidelity Overset Structured Mesh Generation for Marine Hydrokinetic Devices

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.

Emirates Team New Zealand Uses Pointwise for AC72 Hydrodynamics Design

Emirates Team New Zealand Uses Pointwise for AC72 Hydrodynamics Design

The 34th America's Cup will be contested this fall in San Francisco Bay in high-speed, high-tech, hydrofoiling catamarans hitting speeds upwards of 40 kts (more than 46 miles per hour). These new AC72 class catamarans are 72 feet long (22 m), 46 feet wide (14 m) with a wing mast towering 131 feet (40 m) above the water.
