[Paraview] Problems writing Ensight Gold format

[Zhanping Liu]

Hi Erik:

   Debug shows that your cell data files (test*.00) are not in valid EnSight
Gold format.
A valid binary 'Scalar per Element' (i.e., scalar cell data) file begins
with a 80-char description
line, followed by a 80-char line that contains token 'part'. Then comes with
an integer (in binary)
that serves as the part / zone Id. What follows is a list of element (cell)
types with the
associated element (cell) based scalar values. Specifically, each element /
cell type occupies
a 80-char line. The 'block' section should come at the very end of a 'scalar
per element' file,
whereas the 'block' token emerges at the third line (while actually the
aformentioned integer value in binary
--- the part/zone Id is expected) of your file.

   Please note that even a binary EnSight Gold file usually contains chars
(e.g., description
lines and EnSight tokens) and in this case, the chars are encoded in the
file on a 80-char-line basis
and each such line ends with a cariage-return symbol.
   Please reference pp. 536, the EnSight User Manual (
http://vis.lbl.gov/NERSC/Software/ensight/docs82/UserManual.pdf)
to find the valid format for a 'scalar per element' file. Also, you may use
EnSight Format Checker
(http://aero.ist.utl.pt/~rreis/ens_checker.32 and
http://aero.ist.utl.pt/~rreis/ens_checker.64)
to check your EnSight files, though these two checkers are 'necessary' but
not 'sufficient'.
