CM2 SurfMesh T3

current version: 5.4.1 (March 2024)

Surface Triangle Mesh Generator for CAD Models

CM2 SurfMesh T3 is a surface triangle mesh generator based on CM2 TriaMesh Aniso and OpenCascade (OCCT).

Main features:

  • Target mesh size, maximal chordal error, maximal size gradation.
  • CM2 SurfMesh T3 can automatically repair topological errors of the CAD model (it can merge close vertices and close curves).
  • Meshes on the 3D surfaces can be isotropic (equilateral triangles as good as possible) or anisotropic to reduce the number of elements keeping the same chordal error (stretched triangles on fillets for instance).
  • CM2 SurfMesh T3 can generate 6-node triangles with mid-nodes projected onto the exact CAD surfaces (curved triangles) or not (plane triangles).
  • CM2 SurfMesh T3 can read STEP, IGES and B-Rep files or mesh directly any OCCT TopoDS_Shape object.

Complementary Products

CM2 SurfMesh® Q4

CM2 SurfMesh Q4 is the CAD surface (B-Rep, IGES, STEP) all-quad / quad-dominant 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 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.

Training + Custom Developments and Extensions

We love our code. As we have been and are still working hard to develop it, we know it inside out. No one is better suited to help you in many ways.

We are standing by to assist with the integration of our SDK into your programs. Training sessions are available either at your location or in our offices right here in Versailles, France. We’ll be happy to teach you to use our code, to integrate it and get the best out of it to power and enhance your applications.

We are open to suggestions to expand the boundaries of our CM2 MeshTools SDK and CM2 FEM SDK with new features tailored to your specific needs. We can also design and develop exclusive full custom-made code for you.
