Vector Field File Format Conversion: avf2ovf

The avf2ovf program converts vector field files from any of the recognized formats (OVF, VIO) into the OVF 1.0 format.

Launching
The avf2ovf launch command is:

tclsh oommf.tcl avf2ovf [standard options] [-format <text|b4|b8>] \
   [-grid <reg|irreg>] infile >outfile

where

-format <text|b4|b8>

Specify output data format. The default is ASCII text; b4 selects 4-byte binary, b8 selects 8-byte binary. (The OVF format has an ASCII text header in all cases.)

-grid <reg|irreg>

Specify output grid structure. The default is reg, which will output a regular (rectangular) grid if the input is recognized as a regular grid. The option -grid irreg forces irregular mesh style output.

infile

Name of input file to process. Must be one of the recognized formats, OVF 0.0, OVF 1.0, or VIO.

>outfile

Avf2ovf writes its output to stdout. Use the redirection operator ``>'' to send the output to a file.

The -format text and -grid irreg options are useful for preparing files for import into non-OOMMF applications, because all non-data lines are readily identified by a leading ``#,'' and each data line is a 6-tuple consisting of the node location and vector value. Pay attention, however, to the scaling of the vector value as specified by ``# valueunit'' and ``# valuemultiplier'' header lines.

For output format details, see the OVF file description.
