Description

The source-tree is separated into several classes for convenience:

dynamicTopoFvMesh

Mesh class that extends dynamicFvMesh functionality to handle dynamic simplical meshes, which consist of triangle prisms in 2D, and tetrahedra in 3D. Adaptation is driven mainly by mesh-quality and mesh refinement criteria. When used in combination with mesh-smoothing methods, this functionality is expected to suit situations where domain deformation characteristics are not known a-priori. Conservative solution remapping after mesh reconnection is performed automatically. Parallel functionality is also included.

fluxCorrector

Auxiliary library which is used by dynamicTopoFvMesh to perform a correction to velocity fluxes after mesh reconnection.

mesquiteMotionSolver

Class that provides a general interface to the Mesquite mesh smoothing library from Sandia National Labs. The class also performs smoothing for surface meshes using a spring-analogy approach, and is known to work in parallel.

conservativeMeshToMesh

Conservative mesh-to-mesh interpolation class.

mapConservativeFields

Field-mapping utility that works in a manner similar to mapFields in OpenFOAM, using the conservativeMeshToMesh class as a back end. This utility is currently not designed to work in parallel.

Target platform

The master branch is known to work with OpenFOAM-extend. To compile with the OpenFOAM-2.3.x release, switch to the Port-2.3.x branch.
