Thanks for developing the laminar smoke package. it is exciting running the first case. As per readme instructoin i have completed installing the minimalist version. the first case of H2 Toro flames ran succesfully. both unsteady and steady case. How do I plot results(temperature species field residuals etc.)? is there any script?

The post-processing operations (visualization of 2D maps, extraction of variables along a given direction, calculation of integral/mean/max/min quantities, etc) can be carried out using the tools provided by OpenFOAM. I suggest to have a look at the OpenFOAM User's Guide to get familiar with these tools:
cfd.direct/openfoam/user-guide/v6-postprocessing/

In particular, Paraview is the standard postprocessor for OpenFOAM calculations. It is provided together with OpenFOAM in a customized version, called paraFoam:

Recently, I have used laminarSMOKE solvers on one step methane on my blockMesh and finally got my desired results. Now, I'm trying to simulate Soot kinetic mechanism available from the creckmodeling website. My fuel of interest is C2H4 and from there, I want to analyze soot in paraview. To make things clearer, I will list the steps I took for post processing the soot model:

1. I downloaded Soot mechanism from creck website and directed it in solverOptions.
2. I included C2H4 in my 0 folder. (Changed CH4 to C2H4) // correct me if I'm wrong, but I should only have the initial species in my 0 folder right?
3. add more lewis number by overwriting the current one with ToroFlame/F3/laminarBuoyantPimpleSMOKE/constant/lewisNumbers
4. Change the settings in solverOptions. In the postProcessing function, when I turned soot to on, I got this error but I'm uncertain how to include PolimiSoot in dictionary:

--> FOAM FATAL IO ERROR: 
keyword PolimiSoot is undefined in dictionary "/home/hafiz/OpenFOAM/hafiz-6/run/sootingFlame/constant/solverOptions.PostProcessing"

file: /home/hafiz/OpenFOAM/hafiz-6/run/sootingFlame/constant/solverOptions.PostProcessing from line 85 to line 88.

    From function const Foam::dictionary& Foam::dictionary::subDict(const Foam::word&) const
    in file db/dictionary/dictionary.C at line 701.

FOAM exiting

It's the same case when I on formationRates in Output function, this is the error that I got:

-

-> FOAM FATAL IO ERROR: 
keyword listFormationRates is undefined in dictionary "/home/hafiz/OpenFOAM/hafiz-6/run/sootingFlame/constant/solverOptions.Output"

file: /home/hafiz/OpenFOAM/hafiz-6/run/sootingFlame/constant/solverOptions.Output from line 61 to line 64.

    From function const Foam::entry& Foam::dictionary::lookupEntry(const Foam::word&, bool, bool) const
    in file db/dictionary/dictionary.C at line 566.

FOAM exiting

For now, I am stuck on that step. but I will update if I managed to solve the problem here. I'm still unfamiliar with post processing settings.

PS: is there any guide on using laminarSMOKE (besides the tutorial)? so far, I've been mix and match -ing the cases from my OF knowledge and it would be great if I can go deeper into this solver!
