I am exporting my data from Fluent in Ensight Case Gold binary format using **location: Node**. The data for multiple cluster runs is stored sequentially. However, the data from the first 1 s (i.e., the first run) visualizes correctly and smoothly, while the data from subsequent runs (at 2s) appears distorted or pixelated, as shown in the attached file.

Somehow downloading it as a .zip file results in a corrupted zip file, and I will not download each file individually.

Sorry about that, not sure why this happened, I uploaded a zip file at this link hopefuly it’ll work. Thanks!

Timestep 3:
Timestep 4:
But this is coming from your data, ParaView is displaying it fine, its just how the data is.
I do not konw why your data is like this, what if you save it in other formats ?

The `.cas` and `.dat` files saved by Fluent after a run are all correctly visualizing. However, the problem, as far as I understand, is that the underlying mesh indexing or how the data is stored in the subsequent cluster runs is not consistent with the initial run’s geometry (the original `.geo` file). As you can see, timestep 3 marks the end of the first/initial run, and from 4 onward, there’s the subsequent cluster run.

So is this an issue in your data or how VTK/ParaView reads it ?

I think it’s how the data is being written/ being stitched order.
