Class

Foam::mappedPatchBase
|
|
|
|
Description
|
|
Determines a mapping between patch face centres and mesh cell or face
|
|
centres and processors they're on.
|
|
|
|
If constructed from dictionary:
|
|
// Region to sample (default is region0)
|
|
sampleRegion region0;
|
|
|
|
// What to sample:
|
|
// - nearestCell : sample nearest cell
|
|
// - nearestPatchFace : nearest face on selected patch
|
|
// - nearestPatchFaceAMI : nearest face on selected patch
|
|
- patches need not conform
|
|
- uses AMI interpolation
|
|
// - nearestFace : nearest boundary face on any patch
|
|
sampleMode nearestCell;
|
|
|
|
// If sampleMod is nearestPatchFace : patch to find faces of
|
|
samplePatch movingWall;
|
|
|
|
// How to supply offset (w.r.t. my patch face centres):
|
|
// - uniform : single offset vector
|
|
// - nonuniform : per-face offset vector
|
|
// - normal : using supplied distance and face normal
|
|
offsetMode uniform;
|
|
|
|
// According to offsetMode (see above) supply one of
|
|
// offset, offsets or distance
|
|
offset (1 0 0);
|
|
|
|
Note: if offsetMode is 'normal' it uses outwards pointing normals. So
|
|
supply a negative distance if sampling inside the domain.
|
|
|
|
|
|
Note
|
|
Storage is not optimal. It temporary collects all (patch)face centres
|
|
on all processors to keep the addressing calculation simple.
