I have no knowledge of NEK-5000, nor the content of the results
files produced by NEK-5000. However, in my use of ParaView, ParaView
routinely provides moving and distorting meshes in my animations.
For me, there are at least two ways that the moving and distorting
meshes are produced:<br>
<br>
1) If there are vector displacement values supplied at the grid
points, and ParaView's Warp filter is available (that is, not
grayed-out), then the Warp filter will can be used with a scale
value to reduce, amplify, or give true position of the grid,<br>
<br>
2) If one uses the EnSight-formatted simulation results file, and
true-scale deformed mesh plots are the routine case, then EnSight's
*.geom file can contain by time-step the mesh coordinates, and then
without the use of ParaView's Warp filter, true-scale deformed
meshes are obtained automatically. A small EnSight *.case file (an
ASCII-formatted meta file the points to all of the binary files that
contain the simulation results) is attached.<br>

<div>Hello Giuseppe,<br>

Thanks a lot for replying to my query. <br>
<br>

I understand that you are also facing the same issue
of only one time-step's mesh geometry begin loaded
when you try to use Paraview 4.1.0 to visualize your
post-processed data.<br>
<br>
</div>
When you say using Praview 4.1.0 resolved your issue at
the beginning of your email, do you mean you were able
to visualize *.fld* data in Paraview? If so, can you
please send an example database set and the metadata
file?<br>
</div>
<br>
</div>
I am trying to visualize moving-mesh results for the basic
problem of vortex-shedding past a cylinder moving with
prescribed motion. The flow results are rendered as expected
in Paraview for each time step, but the mesh appears
stationary, corresponding to "firsttimestep", as you also
observe too.<br>
<br>
</div>
I appreciate your help, a set to example database will get me
started on using Paraview for visualizing NEK-5000 data.<br>
<br>
<br>

<div style="word-wrap:break-word">Hello Ravi,
<div>although Paraview 4.1.0 solved my issue, now I am
experiencing the same problem you report with some
postprocessed data (but I have a fixed mesh). In my
opinion this happens when the dataset has mesh
information stored on each .f or .fld file. I think
Paraview expects to have mesh information only in the
first file of the dataset, and it is not behaving well
if this is not the case.</div>
<div>I suspect this because if I edit my .nek5000 file and
change the value of firsttimestep setting it to n, then
Paraview correctly visualizes the data of the n-th time
step, but again it cannot display correctly the data of
the following timesteps.</div>
<div>I also can share some example dataset if it can help.</div>
<div>Best regards,</div>

<div>Hello Patrick and Giuseppe,<br>
<br>
</div>
I am also facing the same issue as
Giuseppe did on visualizing the NEK5000
solution data. I have simulated a moving
boundary problem using NEK5000, and have
the output saved in *.fld* format. When
I load the meta file to read the files
in Paraview, only one time-step mesh
geometry is loaded, whereas the field
results of all the time-steps are
available in Paraview.<br>
<br>
</div>
I would appreciate if either of you could
suggest any workaround to read the moving
mesh geometry which is saved for each
time-step of the solution. <br>
<br>
</div>
I am trying to read my NEK5000 output in
version 4.1.0 64-bit Paraview installation.
If you want the data files, please let me
know, I can send them across.<br>
<br>
</div>
Thanks in advance for you help.<br>

<div>Dear Giuseppe,<br>
<br>
</div>
Yes I remember the issue. I have a
test data set, and I just tested it.
It works with version 4.1. Send me
your data set and I'll look at what
we might have missed.<br>

I am a ParaView user, and I am
experiencing some issues with
NEK5000 output format, both with the
4.0.1 and the 4.1 version.<br>
I have found a user already reported
this bug, but I have not found any
solution online. The problem is that
only the first timestep is
visualized, and not the following
ones. If you want, I could send you
an example output (few Mb).<br>
Thank you in advance, best regards.<br>
