[Paraview] Issues Opening Tecplot *.dat File(s)

Tue Apr 11 17:58:58 EDT 2017

Zach,

With recent changes to ParaView (March 15, 2017), I was able to "open"
the file in the most recent development version of ParaView without
getting stuck in an infinite loop, but I did get the following
warnings:

Warning: In /Users/cory.quammen/src/paraview/VTK/IO/Geometry/vtkTecplotReader.cxx,
line 1795
vtkTecplotReader (0x1350d2c00):
/Users/cory.quammen/Desktop/oneram6-prism_tec_boundary.dat; Tecplot
zone record parameter 'SOLUTIONTIME' is currently unsupported.
Warning: In /Users/cory.quammen/src/paraview/VTK/IO/Geometry/vtkTecplotReader.cxx,
line 1789
vtkTecplotReader (0x1350d2c00):
/Users/cory.quammen/Desktop/oneram6-prism_tec_boundary.dat; Tecplot
zone record parameter 'STRANDID' is currently unsupported.
ERROR: In /Users/cory.quammen/src/paraview/VTK/IO/Geometry/vtkTecplotReader.cxx,
line 1902
vtkTecplotReader (0x1350d2c00):
/Users/cory.quammen/Desktop/oneram6-prism_tec_boundary.dat: The record
type 0.317283460316E+02 found in the file is unknown.

The read fails, but hopefully this tells you what is going on.

HTH,
Cory
