Description

MAdLib is a library that performs global node repositioning and mesh adaptation by local mesh modifications on tetrahedral or triangular meshes. It is designed to frequently adapt the mesh in transient computations, or to generate specific meshes from any initial mesh. MAdLib is written in C++.

The adaptation procedure is driven by two objectives:

MAdLib can therefore be used in transient computations in order to maintain a satisfying element quality (moving boundaries, multiphase flows with interface tracking, ...) or/and to apply selective refinements and coarsenings (error estimators based, interface capturing: shocks, free surfaces, ...).

Starting from version 1.1, MAdLib can perform mesh adaptation on boundaries and snap points on a geometry (GEO, STEP, BREP, ...). The handling of a geometrical model is done through Gmsh (nightly built version).

Starting from version 1.2, MAdLib is equipped with anisotropic mesh size fields and operations on metrics.

The steps to perform mesh adaptation with MAdLib are the following:

  1. Dynamic mesh: convert the static mesh database of the external solver to a dynamic mesh database thanks to the Mesh interface of MAdLib.
  2. Dynamic data: convert the static solution in a dynamic one (same interface).
  3. Size field: define a field of desired edge lengths over the domain.
  4. Adaptation: run the adaptation through the Adapt interface.
  5. Back to static: rebuild the static mesh and solution.

You can find a demo class implementing these steps in the Tutorial/ directory.
