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

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.
