I’m attempting to open the results from a transient Fluent simulation in Paraview. My results are in an Ensight Gold format with results written every 0.25 seconds. The simulation was run on a Linux computer cluster. I am getting the following errors in Paraview:
ERROR: In vtkGenericEnSightReader.cxx, line 465

I have tried the usual remove quotes, delete script lines, and save as .case instead of .encas with no luck. I also tried find and replace “/” with “” using MobaTextEditor, Notepad++, and Notepad; however, no occurrences of “/” were found in the file. I turned on special characters viewing and couldn’t see these characters either. Thanks in advance for any help anyone can provide on solving this issue.

Hi @Max_Munson, in ParaView 6 (release candidates now available at [www.paraview.org/download](http://www.paraview.org/download)), there is a new EnSight reader rewritten from the ground up available in the EnSightGoldCombinedReader plugin (Tools menu → Manage Plugins…) that you can load. You might want to try to use that to see if it does better loading your data file.

Using the EnSightGoldCombinedReader plugin gave a new error:

I think the new issue is that my transient simulation exported ensight data every 0.25 seconds of flow-time. Is there a way to tell paraview my time steps I have data for so that it doesn’t try to open data that doesn’t exist? I have also attached my .encas file in case that helps. I can’t upload my entire data set as it’s well over 60 GB.

Please use a file sharing website like [wetransfer.com](http://wetransfer.com), you can split your data in multile parts if needed.

Are you saying this file doesn’t exist?

Indeed. I meant does that file not exist in the full dataset @Max_Munson? I’m trying to understand what you mean by

@mwestphal Sorry it took me a while to respond, but here’s the link to my files: [Box](https://alabama.box.com/s/pvfny7hm5j3fq5kc2ymmv0z4860pqtth).
@cory.quammen Also yes, that file does not exist in the full dataset.

Well, then your data is not complete.

I had Fluent export the ensight data every 0.25 seconds of flow time so that is the data that exists. Is there a way to tell Paraview to only look for data at the times that I have?

I’m afraid the Ensight reader cannot do that and I’m not sure it should.
In your file you define::
```auto
model: 1 "717initcas *****.geo"
```
and
```auto
number of steps: 30388
```
So ParaView expect 30388 geo files if I’m not mistaken.

Even EnSight thinks you’re missing a file:

This did end up being an issue of what Paraview was expecting vs what Fluent exported. I was able to extract the velocity components and magnitude by writing a Python script to rename all of the files to be 1, 2, 3, … and change the .encas file to match. I also added the following line to get what the time steps sizes roughly should be:
“number of steps: 120
time values:
