Hi,

I am new to Paraview. I found a few posts where a .tec file has been opened in Paraview. I am trying to open the attached file in Paraview, but it doesn’t show anything? Any idea why?

.tec is Tecplot file if I’m not mistaken, however your file appears to be empty in ParaView. Maybe this type of tecplot data is not supported.

Yes, it is a tecplot file. I thought all tecplot files can be opened in Paraview. Apparently not.

Are you sure that your file is a valid file? It looks like the keyword `GEOMETRY` is missing.
