<div>yes, Paraview 4.1.0 is working properly with the standard output of NEK5000 (that means, with fixed mesh, and with the mesh data only on the first timestep). I attach an example which works for me.</div>
<div>Hope it helps.</div>

<div>Hello Giuseppe,<br>
<br>
</div>
Thanks a lot for replying to my query. <br>
<br>
</div>
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>

Ravi<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>
<br>
<div>

<div>Sincerely, <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>
<br>

Dear Patrick,<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>
