Class
|
||||
Foam::displacementLayeredMotionFvMotionSolver
|
||||
|
||||
Description
|
||||
Mesh motion solver for an (multi-block) extruded fvMesh. Gets given the
|
||||
structure of the mesh blocks and boundary conditions on these blocks.
|
||||
|
||||
Note: should not be an fvMotionSolver but just a motionSolver. Only here
|
||||
so we can reuse displacementFvMotionSolver functionality (e.g. surface
|
||||
following boundary conditions)
|
||||
|
||||
|
||||
The displacementLayeredMotionCoeffs subdict of dynamicMeshDict specifies
|
||||
per region (=cellZone) the boundary conditions on two opposing patches
|
||||
(=faceZones). It then interpolates the boundary values using topological
|
||||
walking so requires the cellZone to be a layered mesh.
|
||||
|
||||
The boundary conditions on faceZones are currently:
|
||||
|
||||
follow: the faceZone follows the overall mesh displacement.
|
||||
Use this for faceZones on boundary faces (so it uses the
|
||||
proper boundary conditions on the pointDisplacement).
|
||||
|
||||
fixedValue: fixed value.
|
||||
|
||||
timeVaryingUniformFixedValue: table-driven fixed value.
|
||||
|
||||
slip: the second of a pair of faceZones follows the tangential movement
|
||||
specified by the first faceZone. (= removes the normal component).
