CM2 MeshTools SDK
current version: 5.6.0 (June 2025)
Modern, Reliable, Powerful and Fast Mesh Generators for your FEA/CGI Applications
CM2 MeshTools SDK is a powerful C++ library (Software Development Kit) for mesh generation designed for independent software vendors (ISV) and research departments involved in CAD/CAE computations.
CM2 MeshTools SDK provides strong and reliable foundations to power the most demanding Finite Element Analysis (FEA) or Computer-Generated Imagery (CGI) applications.
The SDK includes plane meshers, surface meshers, solid meshers and specialized tools.
The SDK includes also numerous auxiliary functions and classes for structured mesh generation (2d, 3d), general mesh processing (copy, sweeping, merging, transformation…) or line remeshing.
These are gathered into the CM2 MeshTools Core library (free of charge with all paid licenses).
Plane Meshers
CM2 TriaMesh® Iso
CM2 TriaMesh Iso is the Delaunay plane isotropic triangle mesh generator from the CM2 MeshTools SDK for plane equilateral triangle meshes.
CM2 TriaMesh® Aniso
CM2 TriaMesh Aniso is the Delaunay plane anisotropic triangle mesh generator from the CM2 MeshTools SDK for plane stretched triangle meshes.
CM2 QuadMesh® Iso
CM2 QuadMesh Iso is the plane isotropic quad-dominant / all-quad mesh generator from the CM2 MeshTools SDK for plane mixed quadrangle-triangle meshes.
CM2 QuadMesh® Aniso
CM2 QuadMesh Aniso is the plane anisotropic quad-dominant / all-quad mesh generator from the CM2 MeshTools SDK for plane stretched quadrangle-triangle meshes.
Surface Meshers
CM2 SurfMesh® T3
CM2 SurfMesh T3 is the CAD surface triangle mesh generator from the CM2 MeshTools SDK (partially based on the OpenCascade kernel).
CM2 SurfMesh T3 can generate the input surface mesh for CM2 TetraMesh Iso or CM2 TetraMesh Aniso for instance.
CM2 SurfMesh® Q4
CM2 SurfMesh Q4 is the CAD surface quad-dominant / all-quad mesh generator from the CM2 MeshTools SDK (partially based on the OpenCascade kernel). CM2 SurfMesh Q4 can generate the input surface mesh for CM2 HexaMesh Iso for instance.
CM2 SurfRemesh® T3
CM2 SurfRemesh T3 is the surface triangle remesher from the CM2 MeshTools SDK. The initial surface is defined by an all-triangle mesh (STL-mesh, deformed mesh, mesh too coarse or too fine…)
CM2 SurfRemesh T3 can improve/regenerate the input surface mesh for CM2 TetraMesh Iso or CM2 TetraMesh Aniso for instance.
CM2 SurfRemesh® Q4
CM2 SurfRemesh Q4 is the surface quad-dominant / all-quad remesher from the CM2 MeshTools SDK. The initial surface is defined by an all-triangle mesh (STL-mesh, deformed mesh, mesh too coarse or too fine…)
CM2 SurfRemesh Q4 can improve/regenerate the input surface mesh for CM2 HexaMesh Iso for instance.
Solid Meshers
CM2 TetraMesh® Iso
CM2 TetraMesh Iso is the Delaunay solid isotropic tetrahedral mesh generator from the CM2 MeshTools SDK for (as good as possible) equilateral tetrahedrons.
CM2 TetraMesh Iso can fill the volume(s) inside the surface mesh generated by CM2 SurfMesh T3 or CM2 SurfRemesh T3 for instance.
CM2 TetraMesh® Aniso
CM2 TetraMesh Aniso is the Delaunay solid anisotropic tetrahedral mesh generator from the CM2 MeshTools SDK for stretched tetrahedrons.
CM2 TetraMesh Aniso can fill the volume(s) inside the surface mesh generated by CM2 SurfMesh T3 or CM2 SurfRemesh T3.
CM2 HexaMesh® Iso
CM2 HexaMesh Iso is the Delaunay solid isotropic hex-dominant mesh generator from the CM2 MeshTools SDK for solid hybrid bricks (hexahedrons) / wedges (prisms) / pyramids / tetrahedrons meshes.
CM2 HexaMesh Iso can fill the volume(s) inside the surface mesh generated by CM2 SurfMesh Q4 or CM2 SurfRemesh Q4 for instance.
Specialized Tools
CM2 Intersect® T3
CM2 Intersect T3 is the surface mesh fixer from the CM2 MeshTools SDK. The initial and final surface meshes are 3-node triangle meshes.
CM2 Intersect T3 can repair boundary meshes for CM2 TetraMesh Iso or CM2 TetraMesh Aniso for instance.
CM2 Intersect® E2
CM2 Intersect E2 is the contour mesh fixer from the CM2 MeshTools SDK. The initial and final contour meshes are 2-node edge meshes.
CM2 Intersect E2 can repair the input contour mesh for CM2 TriaMesh Iso or CM2 QuadMesh Iso for instance.
CM2 Layers® 2D
CM2 Layers 2D is the plane boundary layers mesh generator from the CM2 MeshTools SDK.
For instance, the domain outside the layers generated by CM2 Layers 2D can be filled by CM2 TriaMesh Iso or CM2 TriaMesh Aniso.
Easy + Efficient Integration
All the CM2 MeshTools SDK mesh generators have a similar interface and logic. Chain them together and produce complex meshes.
For example, start with CM2 SurfMesh T3 to create a surface mesh on the parametric model. Fix any intersections with CM2 Intersect T3 and refine locally with CM2 SurfRemesh T3. Finish with CM2 TetraMesh Iso to produce a high quality solid tetrahedral mesh.
Save IO time by directly interacting with the CM2 MeshTools SDK mesh generators: there is no complex file format.
Strong Foundations
