Summary0002582: Error in chemkinReader and chemkinToFoam CHEMKIN transport data reading
DescriptionIn laminar simulation, transport data is not read by both chemkinReader and chemkinToFoam utilities. It gives the following error message:

In this case, using GRI 3.0, it was strange that the CHEMKIN file only has 110 lines, not the 112 interpreted by OpenFOAM.
Steps To ReproduceThe simulation was based on the tutorial of /tutorials/combustion/reactingFoam/laminar/counterFlowFlame2D, only changing, in thermophysicalProperties file, "chemistryReader foamChemistryReader" to "chemistryReader chemkinReader", and indicating the respective CHEMKINFile, CHEMKINThermoFile and CHEMKINTransportFile paths.

All other files were kept the same.

I ran blockMesh in the main case directory, with normal output.

Then I ran reactingFoam, with the indicated error output.

The chemical kinetic scheme was GRI 3.0, from http://combustion.berkeley.edu/gri-mech/version30/text30.html#thefiles , whose transport data file begins with

AR 0 136.500 3.330 0.000 0.000 0.000
C 0 71.400 3.298 0.000 0.000 0.000 ! *
C2 1 97.530 3.621 0.000 1.760 4.000
C2O 1 232.400 3.828 0.000 0.000 1.000 ! *
CN2 1 232.400 3.828 0.000 0.000 1.000 ! OIS

The only modification in the scheme was to change "THERMO" to "THERMO ALL" in the thermodynamics file.

The CHEMKIN transport modeling and file format are not yet supported and it would take a very significant investment to add this functionality. Take a look at the transportProperties file in OpenFOAM-4.x/tutorials/combustion/chemFoam/gri/chemkin and you will see that it is using an OpenFOAM format with Sutherland transport modeling hard-coded.
