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 described as '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' and is an app. There are nine alternatives to HyperMesh for Windows, Linux and Mac. The best HyperMesh alternative is Gmsh, which is both free and Open Source. Other great apps like HyperMesh are SimFlow, TetGen, NETGEN and ANSA.

SimFlow is a powerful CFD software, focused on engineering and science. It combines an intuitive user interface with the advantages of the open-source OpenFOAM® libraries in something more than a compact OpenFoam® GUI.




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.

NETGEN is an automatic 3d tetrahedral mesh generator. It accepts input from constructive solid geometry (CSG) or boundary representation (BRep) from STL file format.

FEX is a small yet powerful tool to visualize and verify Finite Elements Method models.




SimWorks is a free CFD software built upon established open-source simulation tools integrated into an intuitive GUI. It supports the entire CFD simulation process: CAD import, pre-processing, meshing, running and fully integrated post-processing.



Pointwise 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.
