[vtkusers] EnSight reader

[francesco caruso]

Hello

I've got a set of EnSight files, exported from fluent.
I'd like to know how to import them in vtk
The files are:
dati_fluent.encas
dati_fluent.scl1
dati_fluent.scl2
dati_fluent.scl3
dati_fluent.geo
dati_fluent.vel

which class have I to use?
where can I find any examples?(the examples in tcl in the vtk site read
.case files)

Thanks in advance
Francesco
