CM2 Intersect E2

current version: 5.4.1 (March 2024)

Edge Mesh Intersections Repairer

CM2 Intersect E2 is a specialized tool for repairing edge meshes (2D and 3D).

From one, two or more independent and possibly (self) intersecting contour meshes (2-node edges), this tool fixes all intersections (by splitting edges and adding new nodes at intersection points) to make a valid mesh suitable for instance for a plane meshing with CM2 TriaMesh Iso/Aniso or CM2 QuadMesh Iso/Aniso.

CM2 Intersect E2 can be used conveniently in conjunction with cm2::meshtools1d::remesh_lines (a function of CM2 MeshTools Core included with all licenses).
The former heals the topological errors (intersections, overlappings) and the later remeshes the lines (possibly locally).

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.
