Hello,
I’m trying to open Fluent files on ParaView 5.10.0 but it always crashes when I click on “Apply” button. Please, find in the attached file a simple test case to reproduce the error.
Thanks in advance
Miguel

Hi,
The **vtkFLUENTReader** has each variable name embedded in the source code.
>
Therefore, it will fail if variable names recently introduced in Fluent are included. Since your dat file contains the unsupported number **420** , the following lines need to be removed from the dat file.
> (0 “SV\_DPM\_PARTITION, domain 1, cell zone 9, 9 cells:”)
> (3300 (420 9 1 0 1 1 9)
> (
> End of Binary Section 3300))

Hello,
I have been using this approach for **2D** cases and works fine. However, for **3D** cases (with several millions of cells) I cannot open the file in a simple TXT editor since it is too big (dat file of about 2GB for 10M cells). There is **another way** to open Fluent files in ParaView **5.10**? The weird thing is that older ParaView versions (like **5.7.0** ) can actually open the standard Fluent file. It seems that something has been wrongly modified in the vtkFluentReader for the new versions.
Thanks in advance
Miguel

I always export to ensight format to read fluent results in paraview.
