Detailed Description

A class that represents a tetrahedral mesh.

The TetMesh class is responsible for creating and managing a tetrahedral mesh. It provides functionality to initialize the mesh, compute connectivity between nodes and elements, create a surface mesh, and save the mesh as a VTK file.

Examples

00_sdf_demo.cpp, and 01_sdf_error.cpp.
