5.1 Convert .fld / .chk files into Paraview, VisIt or Tecplot format

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), VisIt (.vtu format) or Tecplot (.dat or .plt format) the user can run the following commands:

• Paraview or VisIt (.vtu format)
  FieldConvert test.xml test.fld test.vtu
• Tecplot (.dat format)
  FieldConvert test.xml test.fld test.dat
• Tecplot or VisIt(.plt format)
  FieldConvert test.xml test.fld test.plt

where FieldConvert is the executable associated to the utility FieldConvert, test.xml is the session file and test.vtu, test.dat, test.plt are the desired format outputs, either Paraview, VisIt or Tecplot formats.
