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:
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.
When converting to .dat
or .plt
format, it is possible to enable output with double precision,
which is more accurate but requires larger disk space. For example, double precision output in
plt. format can be produced with the command:
test.xml.gz
.
