mcv - mesh file converter
mcv [options] [imfile] [omfile] [oxfile]
The mcv program converts Scotch mesh files from and to other external file formats.
File imfile is converted into mesh file omfile, with optional geometry data being put in
geometry file oxfile, if it is available.
When file names are not specified, data is read from standard input and written to
standard output. Standard streams can also be explicitly represented by a dash '-'.
When the proper libraries have been included at compile time, mcv can directly handle
compressed meshes, both as input and output. A stream is treated as compressed whenever
its name is postfixed with a compressed file extension, such as in 'brol.msh.bz2' or
'-.gz'. The compression formats which can be supported are the bzip2 format ('.bz2'), the
gzip format ('.gz'), and the lzma format ('.lzma', on input only).
-h Display some help.
-iifmt Set format of input mesh file, which can be:
bnum Boeing-Harwell format. This is an elemental matrix format. Only square
matrices are supported. In case the file contains several matrices, the num
parameter allow the user to provide the index of the matrix to convert,
starting from 0. When the num parameter is not set, it is assumed to be 0.
s Scotch mesh format.
-oofmt Set format of output mesh file, which can be:
s Scotch mesh format. This is the only possible choice at the time being.
-V Display program version and copyright.
Convert a Harwell-Boeing elemental mesh into a Scotch mesh.
