Pointwise Alternatives: Top Mesh Generation Software for CFD
Pointwise, Inc. has been a cornerstone in computational fluid dynamics (CFD) since 1994, known for its robust software that reliably generates high-fidelity meshes. It supports structured, unstructured, overset, and hybrid meshes, integrating seamlessly with popular CFD solvers like ANSYS FLUENT®, STAR-CCM+®, OpenFOAM®, and SU2. While Pointwise is a powerful solution running on Windows, Linux, and Mac, with a scripting language (Glyph) for automation, users often seek Pointwise alternative options for various reasons – whether it's for open-source flexibility, specific feature sets, or budgetary considerations. This guide explores some of the best alternatives available for your meshing needs.
Top Pointwise Alternatives
When searching for a meshing tool, it's crucial to consider factors such as platform compatibility, licensing (open-source vs. commercial), and specific functionalities like CAD integration or post-processing. Here are some excellent alternatives to Pointwise that cater to diverse requirements.

SALOME
SALOME is a strong open-source Pointwise alternative, providing a generic Pre- and Post-Processing platform for numerical simulation. It's available for Free on Windows and Linux, making it a highly accessible choice for researchers and engineers looking for a comprehensive, no-cost solution.

Gmsh
Gmsh stands out as another excellent open-source Pointwise alternative, designed as a 3D finite element grid generator with a built-in CAD engine and post-processor.
