[Paraview] NEK5000 with ParaView

[Giuseppe Pitton]

Hello Ravi,
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.
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.
I also can share some example dataset if it can help.
Best regards,
Giuseppe

Hello Patrick and Giuseppe,

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.

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.

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.

Thanks in advance for you help.

Sincerely,
Ravi

Dear Giuseppe,

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.

Best regards,
Patrick

Dear Patrick,
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.
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).
Thank you in advance, best regards.
Giuseppe Pitton
