How to model non-premixed turbulent cold flow for methane-air composition. Which solver I should use which include species transport but not combustion ?
Thanks in advance.

Hopefully I entered the right thread..
I am running reactingFoam for an axisymmetric 2D case which has a wedge boundary condition. I modified the BC files in the 0 folder accordingly and when I ran reactingFoam, it gave the following errors:

Code:

I am not sure what these errors mean and how to fix them. I use OpenFoam3.0.1 on Ubuntu 14.04LTE (if that ever helps).

Any helpful response is really appreciated. Thanks.

Solved the problem. There is a patch in my blockMeshDict called 'axis' and had the patch type as empty. Changed the patch type from empty to symmetry and reactingFoam ran perfectly! However, I do not understand a single line of the errors--if anyone cares to explain that would be great!
