Detailed Description

Container and creator for meshes.

A Mesh can consist of Vertices, Edges, Triangles, and nested Meshes. It provides functionality to conveniently create those objects.

In addition to creating the topological information of a mesh, the Mesh class can also be used to add data to the vertices of a mesh, such as function values or also gradient values.

Usage example: precice::mesh::tests::MeshTest::testDemonstration()
