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.
Automating Geometry and Mesh Generation for Heat Exchangers
Maura Gallarotti, a master's student at KTH Royal Institute of Technology in Sweden, used Pointwise Glyph scripting to quickly generate families of candidate heat exchanger designs and to perform parametric studies by changing the dimensions of several geometrical parameters to assess the effect of these parameters on cooling efficiency. With no experience using Pointwise and having never heard about Tcl/Tk or Glyph she was able to write a script to completely automate the grid generation process in less than a week.
CFD Investigation of LBE Rod Bundle Flow
LBE is a eutectic mixture consisting of 45 percent lead and 55 percent bismuth. It is foreseen as a possible coolant for Generation IV nuclear reactor systems. The most interesting properties of LBE in comparison with lead and water are presented in Table 1.
Gas Turbine Combustor Mixing at Cranfield
Natural gas accounts for more than 23 percent of the world's energy production. Although it is not used in airplane engines because of its large storage volume, it has become widespread in industrial gas turbines and is the fuel of choice for many to plug the “energy gap” within the United Kingdom.
Drag Effects of Heating and Cooling Cylinders in Crossflow
The reduction of the drag force on all types and shapes of objects has historically been, and remains, a major focus of aerodynamicists and fluid mechanics researchers everywhere. Aircraft, automobiles, rockets, boats, and a multitude of other devices and components suffer from the ill effects of viscous and form drag.
From CAD to CFD in Five Minutes
Customers have written many articles about how they apply Pointwise for their real applications. We have written many articles describing benefits about the features in Pointwise. However, these articles rarely describe the full meshing process in any detail.
