Leaders in CFD Mesh Generation - Pointwise

Another Fine Mesh

Learn more about us; read Pointwise's blog, Another Fine Mesh.

Pointwise, Inc. creates software used for grid generation and preprocessing for computational fluid dynamics (CFD). Our software product Pointwise® (and before that, our legacy product Gridgen®) is developed for and delivered to engineers and scientists in manufacturing and research organizations worldwide.

Computational Fluid Dynamics - A Virtual Wind Tunnel

Computational fluid dynamics is the computer modeling of the fluid flow around or through a device. Examples would be air over the wing of an airplane and water through a pipe. Engineers in the aerospace industry use CFD to predict aerodynamic lift and drag and engine performance. In the automotive industry, it is used for drag prediction, estimating heating conditions in the engine compartment and for computing the flow in the engine's intake manifold, cylinders and exhaust manifolds. Because CFD reduces the need for expensive testing and gives engineers more insight into their design before it is built, it saves time and money and leads to better designs.

Why Grid Generation is Critical to CFD

The CFD analysis process, illustrated below, begins with a computer-aided design model of the part being analyzed. Next, the flow region around or through the part is divided into numerous discrete elements call a grid or mesh. Pointwise is the software used to generate the grid. Then, the governing equations for fluid flow are solved for each element, including any interactions between elements, to determine the flowfield. As a last step, useful engineering data like forces, moments, heat transfer and visualizations of vortices and other flow structures are extracted from the numerical flowfield using a post-processor.

There are three major steps in the CFD analysis process: meshing, solution and postprocessing.

CFD begins with a mesh on and around the CAD model. The CFD flow solver runs on a compute server The flow is computed at every point in the mesh.

Grid generation is the most time consuming and difficult part of the CFD analysis process. Grid generation often consumes up to 80 percent of the labor hours for a CFD project and is the largest controllable influence on the accuracy of the analysis. Our products are the best solutions available to the grid generation problem. They allow engineers to work with flawed CAD models without any cleanup. Engineers are free to concentrate on producing high quality grids without having to worry about the grid's bookkeeping aspects.

Pointwise Has Almost Three Decades of Meshing Experience - And Counting

Development of Gridgen began in 1984, pre-dating Pointwise. During the period 1987-1994, development of Gridgen was funded by the United States Air Force, and NASA Langley and Ames Research Centers. The Gridgen software developed during this period was widely distributed and used throughout government labs, DoD contractors, and academia. In 1994, Gridgen was privatized through a technology transfer agreement with the U.S. Government, and Pointwise was born. The next-generation product, Pointwise, was released in 2007 and couples Gridgen's time-tested suite of meshing techniques with a modern user interface. The company has grown rapidly since its founding and continues to maintain this growth as more and more engineers discover the value of its products and services.
