FieldConvert is a utility embedded in Nektar++ with the primary aim of allowing the user to
convert the Nektar++ output binary files (.chk and .fld) into a format which can be read by
two common visualisation softwares: Paraview (.vtu format) or Tecplot (.dat format).
FieldConvert also allows the user to manipulate the Nektar++ output binary files by using
some additional modules which can be called with the option -m
which stands for m
odule. Note
that another flag, -r
(which stand for r
ange) allows the user to specify a sub-range of the
domain on which the conversion or manipulation of the Nektar++ output binary files will be
performed.
Almost all of the FieldConvert functionalities can be run in parallel if Nektar++ is compiled using MPI (see the installation documentation for additional info on how to implement Nektar++ using MPI). 1
