Pointwise is described as 'is the choice for CFD Meshing. It's easy to use, highly automated, provides direct interfaces to popular CFD analysis software, and comes with professional tech support'. There are seven alternatives to Pointwise for Linux, Windows and Mac. The best alternative is SALOME, which is both free and Open Source. Other great apps like Pointwise are Gmsh (Free, Open Source), HyperMesh (Paid), enGrid (Free, Open Source) and NETGEN (Free, Open Source).
Gmsh is a 3D finite element grid generator with a build-in CAD engine and post-processor. Its design goal is to provide a fast, light and user-friendly meshing tool with parametric input and advanced visualization capabilities.
HyperMesh is a market-leading, multi-disciplinary finite element pre-processor which manages the generation of the largest, most complex models, starting with the import of a CAD geometry to exporting ready-to-run solver file.
enGrid is an open-source mesh generation software with CFD applications in mind. enGrid uses an in-house development for surface meshing and prismatic boundary layers; a module for hex far-fields will be added in the next release.
ANSA is an advanced multidisciplinary CAE pre-processing tool that provides all the necessary functionality for full-model build up, from CAD data to ready-to-run solver input file, in a single integrated environment.
TetGen is a program to generate tetrahedral meshes of any 3D polyhedral domains. TetGen generates exact constrained Delaunay tetrahedralizations, boundary conforming Delaunay meshes, and Voronoi partitions.
