Member Function Documentation

◆ unregisterMesh()

void unregisterMesh ( const faMesh &  mesh)
static

Unregister the faMesh from its associated polyMesh to prevent triggering on polyMesh changes etc.

Definition at line 38 of file faMeshTools.C.

References objectRegistry::checkOut(), mesh, fvMesh::thisDb(), and ensightPTraits< Type >::typeName.

Here is the call graph for this function:

◆ forceDemandDriven()

void forceDemandDriven ( faMesh &  mesh)
static

Force creation of everything that might vaguely be used by patches.

This is fairly horrible.

Definition at line 50 of file faMeshTools.C.

References polyMesh::globalData(), and mesh.

Here is the call graph for this function:

◆ newMesh()

Foam::autoPtr< Foam::faMesh > newMesh ( const IOobject &  io,
const polyMesh &  pMesh,
const bool  masterOnlyReading,
const bool  verbose = false 
)
static

Read mesh or create dummy mesh (0 faces, >0 patches).

Works in two modes according to masterOnlyReading: true : create a dummy mesh for all procs false: checks locally for mesh directories and only creates dummy mesh if not present

Here is the call graph for this function:

◆ loadOrCreateMesh()

Foam::autoPtr< Foam::faMesh > loadOrCreateMesh ( const IOobject &  io,
const polyMesh &  pMesh,
const bool  decompose,
const bool  verbose = false 
)
static

if 0 faMeshTools::forceDemandDriven(mesh); faMeshTools::unregisterMesh(mesh); #endif

Here is the call graph for this function:

◆ readProcAddressing()

Foam::mapDistributePolyMesh readProcAddressing ( const faMesh &  mesh,
const autoPtr< faMesh > &  baseMeshPtr 
)
static

Read decompose/reconstruct addressing.

Here is the call graph for this function:

◆ writeProcAddressing()

void writeProcAddressing ( const faMesh &  mesh,
const mapDistributePolyMesh &  faDistMap,
const bool  decompose,
autoPtr< fileOperation > &&  writeHandler,
const faMesh *  procMesh = nullptr 
)
static

Write decompose/reconstruct addressing.

Parameters
mesh
faDistMap
decomposerunning in decompose vs reconstruct mode
writeHandlerfile handler
procMesh(optional) processor mesh in reconstruct mode
Note
Since the faMesh holds a reference to a polyMesh, in reconstruct mode it will refer to the base mesh, but we need a means to proc addressing into the processor locations. This is the purpose of the additional procMesh reference

◆ flattenEdgeField() [1/2]

static tmp< Field< Type > > flattenEdgeField ( const GeometricField< Type, faePatchField, edgeMesh > &  fld,
const bool  primitiveOrdering = false

Optionally use primitive patch edge ordering
