Hi, Julien, I use the ParaView v5.13.1, which should has already support the Fluent CFF I think.
Here are xxx.cas.h5 and xxx.dat.h5 generated from fluent, now I try to post them by ParaView.
When I load the xxx.cas.ht by “Fluent CFF Case Reader”, it looks like ok
**But, errors about HDF still occurred when I load the “xxx.dat.h5” by “Tecplot reader”**
Looking forward to your reply. Thank you.

`.dat.h5` file should not be opened directly, just open the `.cas.h5` file.

you mean what I need to do is just only load the xxx.cas.h5?
xxx.dat.h5 no need load by ParaVIew which maybe load auto after load the xxx.cas.h5,right?
But it looks like nothing after I load the xxx.cas.h5 by ParaView, what can I do to view the data,
like velocity and pressure，and I play there is nothing different.
Do I need write to cas and dat without h5 by fulent according “[https://www.youtube.com/watch?v=uN09vQgkslI&t=81s](https://www.youtube.com/watch?v=uN09vQgkslI&t=81s)” ?

Just select them in the combo box instead of solid color

Thank you for your reply. My main purpose is to use Paraview to create a more dynamic presentation of this airplane model’s data. Specifically, when I click on the triangle, I want to be able to see changes such as velocity, pressure, temperature, etc. This CAS model was built using Fluent, which I’m not particularly familiar with. Additionally, I’m new to Paraview. Could you please help me figure out what I should select from the following images so that when I click on the triangle, I can see the desired changes? Thank you

Uploading: a6-sa-450.cas.h5…
here is cas file, dat file size is 170MB, maybe too large, always upload failed, I will try send dat file by email

Here is the two files link: “[https://we.tl/t-p1q03B3I7k](https://we.tl/t-p1q03B3I7k)”.
I’m not sure my method work with paraview 5.13.1 is wrong or if there is indeed a lack of data.
Thank you!

Like this ?
Just select the array you want to display.

Thank you for your reply.
When I click on the triangle which has been circled by red line, nothing happens. Is it because there is too little data or did I operate incorrectly? Thank you

This is called the “play button” and it has no effect because there is no time steps in your data.
