Extract patch or faceZone surfaces from a polyMesh.
Depending on output surface format triangulates faces.
- Region numbers on faces no guaranteed to be the same as the patch indices.
+ Region numbers on faces not guaranteed to be the same as the patch indices.
Optionally only extracts named patches.
+ Optionally filters out points on faceZones, feature-edges and

If run in parallel, processor patches get filtered out by default and
the mesh is merged (based on topology).
+Usage

+Class
+ Foam::multiDisplacementMotionSolver
+
+Group
+ grpMeshMotionSolvers
+
+Description
+ Mesh motion solver for a polyMesh. Applies multiple (displacement) motion
+ solvers in order.
+
+ Not very efficient : all displacementMotionSolvers store a copy
+ of the initial points (points0) and the displacement (pointDisplacement
+ or also cellDisplacement).
+ Used to combine large-scale, implicit displacement smoothing (e.g.
+ displacementLaplacian) with point smoothing.
+
+Usage
+ Example of the dynamicMeshDict specification:
+ \verbatim
+ motionSolver multiDisplacement;
+ solvers
+ {
+ // Solve finite volume laplacian to efficiently smooth displacement
+ // (not point locations)
+ displacementLaplacian
+ {
+ motionSolver displacementLaplacian;
+ diffusivity uniform;
+ }
+
+ // Apply few iterations of smoothing of point locations
+ displacementPointSmoothing
+ {
+ motionSolver displacementPointSmoothing;
+ pointSmoother laplacian;
+ nPointSmootherIter 10;
+ }
+ }
+ \endverbatim
+
+Note
+ When using displacementLaplacian: the default behaviour for the
+ cellDisplacement is to apply fixed value boundary conditions (by averaging
+ point values) only to those pointDisplacement boundary conditions that
+ are fixed value. Quite a few point boundary conditions (e.g. surfaceSlip,
+ edgeSlip) are not so require an explicitly provided cellDisplacement
+ field with 'cellMotion' boundary conditions for those patches.

+
+Description
+ Quality-based under-relaxation for run-time selectable point smoothing. WIP.
+
+Usage
+ \table
+ Property | Description | Required | Default value
+ untangler | pointSmoother for untangling | yes |
+ untangleQ | quality below which untangling is applied | yes |
+
+ pointSmoother | pointSmoother in 'normal' mode | yes
+ minQ | quality below which pointSmoother is applied | yes
+ nPointSmootherIter | max number of iterations
+ \endtable
+
+ Example of the motion solver specification in dynamicMeshDict:
+ \verbatim
+ motionSolver displacementSmartPointSmoothing;
+ displacementSmartPointSmoothingCoeffs
+ {
+ //- Overall max number of smoothing iterations
+ nPointSmootherIter 10;
+
+ //- If any faces have quality below untangleQ apply untangler
+ untangleQ 0.001;
+ untangler laplacian;
+
+ //- If any faces have quality below minQ apply 'normal' smoother
+ minQ 0.9;

+
+Description
+ Geometric Element Transformation Method (GETMe) point smoother. Points are
+ moved in a direction normal to the face of the dual element. This tends to
+ orthogonalise elements. This method can "push" as well as "pull".
+
+ The original references for this method only formulate it for a limited
+ variety of specific polyhedra. This version is written for arbitrary
+ polyhedra, and most closely follows the following reference:
+
+ \verbatim
+ "Fast smoothing of mixed volume meshes based on the effective geometric
+ element transformation method"
+ Dimitris Vartziotis, Joachim Wipper,
+ Comput. Methods Appl. Mech. Engrg. 201-204 (2012) 65-81
+ \endverbatim
+
+ This implementation does not include the various specific measures employed
+ in the referred article to improve the quality of types of irregular
+ polyhedra. It also does not use the same quality criteria as these are only
+ suitable for cell vertices with exactly three connecting edges.

+ - or .eMesh in or a known format (read from constant/triSurface)
+ - frozenPointsZone : empty or name of pointZone containing points

+
+Description
+ Displacement by attraction to nearest point. Use in a
+ displacementMotionSolver as a bc on the pointDisplacement field.
+
+ Needs:
+ - file : name of edgeMesh. Either:
+ - .extendedFeatureEdgeMesh (read from constant/extendedFeatureEdgeMesh)
+ - or .eMesh in or a known format (read from constant/triSurface)
+ - frozenPointsZone : empty or name of pointZone containing points
+ that do not move
+ - velocity : maximum displacement velocity

+Class
+ Foam::patchToPoint
+
+Description
+ A \c topoSetPointSource to select points associated with given patch(es).
+
+ Operands:
+ \table
+ Operand | Type | Location
+ output | pointSet | $FOAM_CASE/constant/polyMesh/sets/\<set\>
+ \endtable
+
+Usage
+ Minimal example by using \c system/topoSetDict.actions:
+ \verbatim
+ {
+ // Mandatory (inherited) entries
+ name <name>;
+ type pointSet;
+ action <action>;
+
+ // Mandatory entries
+ source patchToPoint;
+
+ // Conditional mandatory entries
+ // Select either of the below
+
+ // Option-1
+ patches
+ (
+ <patchName1>
+ <patchName2>
+ ...
+ );
+
+ // Option-2
+ patch <patchName>;
+ }
+ \endverbatim
+
+ where the entries mean:
+ \table
+ Property | Description | Type | Req'd | Dflt
+ name | Name of pointSet | word | yes | -
+ type | Type name: pointSet | word | yes | -
+ action | Action applied on points - see below | word | yes | -
+ source | Source name: patchToPoint | word | yes | -
+ \endtable
+
+ Options for the \c action entry:
+ \verbatim
+ new | Create a new pointSet from selected points
+ add | Add selected points into this pointSet
+ subtract | Remove selected points from this pointSet
+ \endverbatim
+
+ Options for the conditional mandatory entries:
+ \verbatim
+ Entry | Description | Type | Req'd | Dflt
+ patches | Names of patches | wordList | cond'l | -
+ patch | Name of patch | word | cond'l | -
+ \endverbatim
+
+Note
+ The order of precedence among the conditional mandatory entries from the
+ highest to the lowest is \c patches, and \c patch.
