change CGNS export from hdf5 to adf

t.teschner · October 27, 2018, 06:47

I am aware that the new file standard for CGNS files is hdf5 now due to its parallel capabilities over the adf format, however, I would like to continue to support adf. I saw on https://www.pointwise.com/doc/user-m...utes/cgns.html that I can switch between hdf5 and adf as a file type for my CGNS file export, however, it seems I can no longer set the solver attributes in pointwise? Is there any way to write your CGNS files with the adf standard?

The adf/hdf5 option is under the CAE, Set Solver Attributes... menu.

This choice should be made before exporting via the File, Export, Grid... menu.

*** EDIT ***

I just tested with V18.2R1 - there is a bug. No matter which option is set (ADF/HDF5) the CGNS file is always written as HDF5.

Please contact Pointwise at support@pointwise.com or the website and log a bug.

thats the thing, I can't access "set solver attributes" when I have CGNS selected as solver (so I couldn't even try to set hdf5 or adf). I figured in the end it would just be better to rebuild CGNS with hdf5 which I eventually managed to do, so I can use my files now again, but thanks for the help and checking

If I understand correctly, what you described is even worse!

Are you saying that in your Install of Pointwise:

CGNS is the current solver (CAE, Select Solver...)
The status bar (at the bottom left) shows CGNS
The CAE, Set Solver Attributes... menu item is disabled?

Which version of Pointwise are you using?

Please log a bug with Pointwise support if what I am describing is true.

Yes, what you are saying is correct. I work under UNIX so I have configured my bashrc script to always load pointwise for convenience, in this case pointwise version 18.0R2. However, if I use the latest version available to me (V18.0R4) then I am able to access the set solver attributes. Seems to be a bug indeed. I updated my bashrc script so it is working fine now for me, will log a bug anyways. Thanks for your help.

Do NOT log a bug. The version you are using is very old.

The ability to choose ADF/HDF5 was added in V18.1R1 by the feature PW-18081 Option to Export CGNS with HDF5 or ADF

I strongly suggest you upgrade to the latest build V18.2.
