Previous: Bitmap File Format Conversion:
The avf2odt program converts rectangularly meshed vector field
files in any of the recognized formats
(OVF, VIO) into the ODT 1.0 data table format.
Making Data Tables from Vector Fields:
The avf2odt launch command is:
tclsh oommf.tcl avf2odt [standard options] \
[-average <space|plane|line|point>] [-axis <x|y|z>] \
[-region <xmin> <ymin> <zmin> <xmax> <ymax> <zmax>] \
- -average <space|plane|line|point>
- Specify type of averaging. Space outputs 1 data line consisting
of the average vx, vy and vz field values in the selected
region (see -region option below). For example, in magnetization
files, vx, vy and vz correspond to Mx, My and Mz.
If plane or line is selected, then the output data table
consists of multiple lines with 4 or 5 columns respectively. The last
3 columns in both cases are the vx, vy and vz averaged over
the specified axes-parallel affine subspace (i.e., plane or line). In
the plane case, the first column specifies the averaging plane
offset along the coordinate axis normal to the plane (see -axis
option below). In the line case, the first 2 columns specify the
offset of the averaging line in the coordinate plane perpendicular to
the line. If -type is set to point, then no averaging is
done, and the output consists of 6 column data lines, one line for
each point in the selected region, where the first 3 columns are the
point coordinates, and the last 3 are the vx, vy and vz
values at the point.
This parameter is optional. The default value is space.
- -axis <x|y|z>
- For the -type plane and -type line averaging types,
selects which subset of affine subspaces the averaging will be
performed over. In the plane case, the -axis represents
the normal direction to the planes, while for line it is the
direction parallel to the lines. This parameter is ignored if
-type is space or point. Optional; default is
- -region <xmin> <ymin> <zmin> <xmax> <ymax> <zmax>
- Axes-parallel rectangular box denoting region in the vector field
file over which data is to be collected. The locations are in
problem units (typically meters). A single hyphen, ``-'', may be
specified for any of the box corner coordinates, in which case the
corresponding extremal value from the input file is used. Optional;
the default, -region - - - - - -, selects the entire input file.
- Name of input file to process. Must be one of the recognized formats,
OVF 1.0 or VIO, in a rectangular mesh subformat. Required.
- Avf2odt writes its output to stdout. Use the redirection operator
``>'' to send the output to a file. For output format details,
see the ODT file description.
Note: The mx, my and mz average magnetization values
reported by mmSolve2D exclude points
with 0 saturation magnetization. Such points are included by
avf2odt, so the data table output from this program will probably
not agree with that directly output by mmSolve2D if there are
any such regions.
