No it isn't a bug. The legacy VTK file format (the format your example file=
=20
is in) only supports one SCALAR. At the time this file format was created,=
=20
VTK only allowed you to have one scalar array. If you needed more than one,=
=20
it needed to be in field data. Try making the changes I have noted in your=
=20
example below. The new XML-based VTK file formats do not have this=
 limitation.

FIELD FieldData 1

>LOOKUP_TABLE default  <-- remove this line too

erreur 1 216 float <-- indicates that this is a single-component array with=
=20
216 entries
