We’re excited to announce the release of Gambit 2.4.6, the latest update that brings focused improvements, important bug fixes, and performance refinements to enhance stability and user experience.

Solution: Gambit 2.4.6 exports mesh format version 5 (.msh). Fluent 2019+ expects version 7. Use a conversion script:

fluent 3ddp -g -i convert_v5_to_v7.jou

Input a tetrahedral mesh, and with three clicks, Gambit 2.4.6 converts it to polyhedral cells. This reduces cell count by 50-70% while improving solution accuracy—a feature so good that ANSYS re-implemented it poorly in later meshers.

The full installation is under 500 MB. It runs on a 10-year-old laptop with 2 GB RAM, whereas ANSYS Fluent Meshing 2024 requires 16 GB minimum.
