[Paraview] Ensight Particle format problem

[Jortner, Jeff]

Hi,
If you are using the measured particles then you have to specify them
under the geometry section using the line:

Measured: 1  viksit_ascii.geo

You must also have both a model line and measured line.

You can define the particles as point elements and view them that way
instead of using measured data. If you have access to EnSight, you can
use the included program ens_checker to verify your EnSight case and
data files.

Hi all,

I'm trying to figure out how the Ensight particle file format works
(writing a program for the file in ASCII or Binary should be easier than
figuring it out how it works!). In the documentation, it is given as the
Ensight Measured/Particle file format - but I'm not sure if this means
its a .Geo file, or a scalar/vector file.

My question basically is - how would such a format be represented?
What I do currently is: (taken from the manual)

viksit_ascii.case
--
FORMAT
type: ensight gold

GEOMETRY
model:  1       viksit_ascii.geo


and

viksit_ascii.geo
--

This is a simple measured geometry file

307 0.00000E+00 0.00000E+00-1.50000E+00


But loading it into Paraview doesn't make it appear. Could anyone shed a
light on as to why not - What am I doing wrong?

I had 2 further questions -
a) Once I do get these points to show up, how would I assign say, a 3d
sphere glyph or similar to each of these points? Am I right in assuming
that this can be done by the materials format?

b) If I had to limit these particles in a sort of a box (say a cube with
these particles moving about) - how would I achieve the bounding such
that they don't move out of that particular set of coordinates?)

Thanks,
Viksit
