Pointwise has released a major update to its computational fluid dynamics (CFD) mesh generation software. With its origins in a multi-year development effort funded by the US Air Force for overset grid assembly, this latest Pointwise release includes a suite of tools that provide increased automation and flexibility in mesh topology creation, mesh types and mesh quality assessment.
Pointwise 18.1 Released for CFD:
From point of view of mesh topology, Pointwise now includes Frameworks, the ability to generate meshes within coordinate systems, local to geometric components (for example, a fuel tank) and then transform them into a global coordinate system (for example , placing the fuel tank below the aircraft’s wing). A new top-down technique called “Build Blocks” provides a rapid volume mesh creation around selected meshes such as would be used for overst refinement. The ability to create surface meshes that are independent of the geometry model topology has been simplified with the addition of a curve drawing mode that does not rely on the geometry model’s parametric space.
Voxel blocks are a new top-down, volume mesh generation technique that quickly encapsulates a boundary layer in a resolved mesh within a Cartesian grid. The mesh adaptation through the use of sources for overset interpolation remediation now influences the surface mesh in addition to the volume mesh.
Mesh quality assessment now includes filters that can be limited to a range of metric values. Filters also provide the basis for creating cloud clouds for mesh adaptation through the new Snapshot capability. Planar cuts through a mesh can persist outside of the Examine command to monitor the effect of mesh changes on mesh quality.
Pointwise Version 18.1 also extends the software’s plugin API to provide users with the ability to add, at runtime, their own mesh import capabilities. V18.1 is delivered with new mesh importers for FUN3D, CFD ++, OpenFOAM, SU2, CRUNCH, ANSYS CFX and ANSYS Fluent. The software includes dozens of other smaller features and defect corrections.
