Description
|
||||
Sample field data with a choice of interpolation schemes, sampling options
|
||||
and write formats.
|
||||
|
||||
Keywords:
|
||||
|
||||
\param setFormat : set output format, choice of \n
|
||||
- xmgr
|
||||
- jplot
|
||||
- gnuplot
|
||||
- raw
|
||||
|
||||
\param surfaceFormat : surface output format, choice of \n
|
||||
- null : suppress output
|
||||
- foamFile : separate points, faces and values file
|
||||
- dx : DX scalar or vector format
|
||||
- vtk : VTK ascii format
|
||||
- raw : x y z value format for use with e.g. gnuplot 'splot'.
|
||||
- obj : Wavefron stl. Does not contain values!
|
||||
- stl : ascii stl. Does not contain values!
|
||||
|
||||
\param interpolationScheme : interpolation scheme, choice of \n
|
||||
- cell : use cell-centre value; constant over cells (default)
|
||||
- cellPoint : use cell-centre and vertex values
|
||||
- cellPointFace : use cell-centre, vertex and face values. \n
|
||||
-# vertex values determined from neighbouring cell-centre values
|
||||
-# face values determined using the current face interpolation scheme
|
||||
for the field (linear, limitedLinear, etc.)
|
||||
|
||||
\param fields : list of fields to sample
|
||||
|
||||
\param sets : list of sets to sample, choice of \n
|
||||
- uniform evenly distributed points on line
|
||||
- face one point per face intersection
|
||||
- midPoint one point per cell, inbetween two face intersections
|
||||
- midPointAndFace combination of face and midPoint
|
||||
|
||||
- curve specified points, not nessecary on line, uses
|
||||
tracking
|
||||
- cloud specified points, uses findCell
|
||||
|
||||
Option axis: how to write point coordinate. Choice of
|
||||
- x/y/z: x/y/z coordinate only
|
||||
- xyz: three columns
|
||||
(probably does not make sense for anything but raw)
|
||||
- distance: distance from start of sampling line (if uses line)
|
||||
or distance from first specified sampling point
|
||||
|
||||
Type specific options:
|
||||
uniform, face, midPoint, midPointAndFace : start and end coordinate
|
||||
uniform: extra number of sampling points
|
||||
curve, cloud: list of coordinates
|
||||
|
||||
\param surfaces : list of surfaces to sample, choice of \n
|
||||
- plane : values on plane defined by point, normal.
|
||||
- patch : values on patch.
|
||||
