.dat file that was exported from Tecplot, I want to open it in ParaView. Import .dat file, error occurred in ParaView.Below is some information from my .dat file:

```auto

Open this file in ParaView 5.12.0-RC1 on ubuntu20.04.6 LTS, but I get two warnings:

```auto
Warning: In vtkTecplotReader.cxx, line 1941 vtkTecplotReader (0x6e6a710): /home/zhang/1.dat; Tecplot zone record parameter 'STRANDID' is currently unsupported.
Warning: In vtkTecplotReader.cxx, line 1947
vtkTecplotReader (0x6e6a710): /home/zhang/1.dat; Tecplot zone record parameter 'SOLUTIONTIME' is currently unsupported.

```

the geometry looks like this:

 ![iShot_2024-07-18_23.54.58](https://discourse.paraview.org/uploads/default/original/2X/5/50a0964d34a4a59495995fc2aae3b57fe8549586.jpeg)  
Which looks like either points or cell ordering information is being read wrong.

Thanks for opening the issue ([https://gitlab.kitware.com/paraview/paraview/-/issues/22705](https://gitlab.kitware.com/paraview/paraview/-/issues/22705)).

I’m not familiar with tecplot, maybe your element are not defined in the correct order ?

Thank you for your reply. Indeed, it is very likely that my elements were not defined in the correct order. Thanks again!
