Regarding your question, "Do you have any EnSight Gold-Format
files greater than 4GB?" No, the largest EnSight *.geom file I
have is 1 GB.<br>
<br>
I just tried it in PV v5.0.0. Reading the datum set and running
through 67 time steps did not cause any problems. I don't think
this *.geom file is big enough to expose any of the PV reader
reader problems you are experiencing.<br>

undersatand how can the file fragmentation affect it's
readability and parsing. Even if the file has thousands of
fragments and "brain-damaging" :) runlist in many extended
FILE records on NTFS partition, your program, if it uses
Win API, will see it like a solid file (althougt there
will be very low performance of sequental access). So
there should be no any faults on reading highly fragmented
files.<br>

<span name="Samuel Key" class="">I have checked out the

</span></div>
<span name="Samuel Key" class="">I think the problem is not a
fragmentation but a <b>file size</b>. Some 32-bit-like
relicts or so in EnSight reader (it's just a guess, sorry if
I'm wrong). But my hypothesis does not asks the question why
does the bug affect only Windows versions... Maybe there are
differences between versions concerning data types. Do you
have any >4 GB binary EnSight 6 or Gold case to test? I
can't (not allowed) to publish my case and it's also big
enough for upload (although theoretically I can do it from my
home PC).<br>

<br>
Let us focus on MS Windows for a moment. The NTS file
system and the use of the file system by the O/S is not
quite as it should be.<br>
<br>
In my experience, the above combination routinely
creates an unbelievable number of file fragments. Think
in terms of confetti. As time goes by, the fragmentation
builds. Even though you have a respectable amount of
RAM, the free space itself on the disk driver can get
rather disorganized.<br>
<br>
You can start by using the MS-supplied defrager. Run
this utility five to seven times in a row and things
might start looking better. However the free-space can
still remain disjointed. Personally, I prefer a 3rd
party utility for organizing and defraging the NTS file
system (for example, PerfectDisk from Raxco). Even this
utility has to run a couple of times plus once during
the O/S re-boot phase to get a decent amount of
consolidated free space and a somewhat consolidate O/S
paging file. All of this has to be done on the O/S
partition (usually C:) and the partition where you read
in the 5+ GB Ensight Geometry file. <br>
<br>
On my machine, the MS Win7 O/S has its own partition
(100GB \C:) plus another smaller dedicated partition for
a second paging file (28GB \F:). All of my simulation
work including the EnSight results file-sets reside on
an entirely separate disk drive (280GB \G: that now
needs to be even larger). The 3rd party file
consolidation software runs "day and night" on the \G:
partition.<br>
<br>
Just to emphasize the point, copying the 5+ GB EnSight
geometry file on to workstation can result in many
scattered fragments even when the free-space starts out
consolidated. If the free space is not consolidated, the
file fragmentation will be even more. <br>
<br>
The attached screen capture, shows the O/S managed
paging-file (brown) in the \C: partition is beginning to
fragment.<br>
<br>
If you go down this path and it helps, please let me
know the outcome.<br>

<p>About transferring files from
Linux to Windows. I use binary
EnSight files because CFX
converter fails to write so
large files in ASCII format.
But I tried to convert from
CFX to EnSight (binary) on the
same Win-7 x64 machine with
ParaView. Both installed
versions (4.3 and 5.0) failed
to open the geometry (I
unchecked all fields).
ParaView 4.3 crashed, ParaView
5.0 just cannot open file...</p>
<p>I think that the root cause
may be a geometry file size.
It is 4.9 GiB (5.3 GB), mesh
have about 150 millions of
cells, not 600 thusands like
in your case. Its possible
that ParaView for Windows
cannot process so large
EnSight files, although the
Linux version reads in this
geometry and displays outline
(swapping is so intensive so I
cannot displaye something
else).<br>

For what it is
worth, I use
ParaView
(ParaView-5.0.0-Qt4-OpenGL2-Windows-64bit)
on Windows-7
64bit. I just now
tested two
medium-sized,
EnSight
Gold-formatted
simulation results
files (600,000
finite elements)
and both worked.<br>
<br>
In the past, I
have had
difficulty with
the EnSight
ASCII-formatted
*.case file when
moving the
simulation results
(*.case file and
friends) from MS
Windows to EnSight
running on a linux
platform. It was
necessary to pass
the ASCII *.case
file through a
'dos2unix' filter.
Transferring files
the other way
might have the
same problem???<br>
<br>
Hope this helps.<span><font

<div>Hello. We
use Ansys CFX
in our work
but the
standard
post-processor
CFD-Post
consumes one
of Ansys
licenses while
Paraview is
free. So I
often make
pictures for
reports with
ParaView to
preserve Ansys
license for
another
users/needs
(because other
users are not
familiar with
ParaView and
CFD-Post may
consume
general "acfd"
license
feature that
may be used
for
calculations).
I convert CFX
results to
EnSight Gold
format in CFX
Solver Manager
(Export
Results) and
then open in
ParaView. It
was working
well on Linux
(CentOS 6.7
x64, Ubuntu
12.04 x64 with
updates) but
now I work
with large
files and I
need to use
another
machine that
has 128 GB of
RAM and runs
Windows-7 x64.<br>
</div>
I downloaded
and installed
the following
version:
ParaView-5.0.0-Qt4-OpenGL2-Windows-64bit.exe<br>
</div>
When I open my
EnSight-format
file I receive
the error
message that
geometry file
cannot be
read. I tried
to move
EnSight files
to a simple
location
(D:\Temp) and
renamed them
(test.case,
test.geom +
edited the
case to change
geometry file
name to
"simple" one).
The same
result, it
cannot find
geometry
file... Full
error message
is as follows:<br>

OK, I tried to
open it in
ParaView 4.3.
It says
nothing (only
border of the

appears) and
crashes. At
that moment I
see in the
status bar
that EnSight
reader
progress is
100%.<br>
<br>
</div>
<div>Both
ParaView 5.0.0
and 4.3 was
tested with
EnSight files
exported on
Linux and
Windows
machine. It
didn't help.<br>
</div>
<div><br>
</div>
OK, I tried to
export CFX
results to
CGNS format.
ParaView 5.0.0
(without MPI)
cannot read
it, so I fed
it to ParaView
4.3. It says
that its
"unable to
filed any
meshes".<br>
<br>
</div>
<div>I also
performed an
experiment on
my Linux
laptop. It has
only 16 GB of
RAM so its
unreal to work
with such a
big file on
this machine
but it reads
the same
EnSight case
and displays
the domain! No
arrays
selected (mesh
only), swap
file grows up
to 8 GB but
the file opens
without errors
and crashes.
It's only a
test because I
have not any
Linux machine
with memory
large enough
(our Linux
cluster has
128 GB of RAM
on every node
including
master but it
has very poor
video).<br>
</div>
<div><br>
</div>
I switched to
CFD Post for
this case but
I want to know
are there any
workarounds to
open my
EnSight-format
results in
ParaView for
Windows.<br>
<br>
