The avfdiff program computes differences between vector field files
in any of the recognized formats
(OVF, VIO). The input data must lie on rectangular meshes with
Vector Field File Difference:
The avfdiff launch command is:
tclsh oommf.tcl avf2ovf [standard options] file-0 file-1 [... file-n]
- Name of input file to subtract from other files. Must be either
an OVF 1.0 file in the rectangular mesh subformat, or an VIO file. Required.
- Name of first input file from which file-0 is to be subtracted.
Must also be either an OVF 1.0 file in the rectangular mesh
subformat, or an VIO file, and must have the same dimensions as
- Optional additional files from which file-0 is to be
subtracted, with the same requirements as file-1.
For each input file file-1 through file-n, a separate output
file is generated, in the OVF 1.0 format. Each output file has a
name based on the name of corresponding input file, with a -diff
suffix. If a file with the same name already exists, it will be
For output file format details, see the OVF file
