DUNE MMesh Module: CGAL Triangulation Interface for 2D and 3D Simulations

The DUNE MMesh module implements a grid interface for the DUNE framework, wrapping CGAL triangulations in two and three dimensions. It was authored by Samuel Burbulla from the University of Stuttgart. The module can export a prescribed set of cell facets as a one-dimensional interface grid and supports remeshing when this interface moves.

Use Cases

• Implementing adaptive mesh refinement workflows based on the described remeshing capability.
• Creating interface-coupled simulations using the module's ability to export cell facets as a separate grid.
• Developing finite element solvers that leverage the wrapped CGAL triangulation structures.
• Testing and benchmarking mesh generation algorithms within the DUNE framework.

Strengths

• Implements a standard grid interface for the established DUNE framework.
• Supports both 2D and 3D triangulations via the CGAL library.
• Provides specific functionality for interface grid extraction and dynamic remeshing.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
