The flamelet table generation tool of FineOpen, TabGenChemistry, requires the chemical mechanism in .chm format as input.

I have the chemical mechanism in the following formats: .inp, .cti and .xml. Is there a tool to transform one of these formats into a .chm file?

Sir,

TabGen-chemistry is using chem1d (1D-chemistry solver of TU/Eindhoven) as a kernel. A chemical mechanism in Chemkin-format can be transformed into a chm-file (chem1d-native format) by using a pre-processing tool of chem1d ("trot"). We are not a priori giving users access to this tool. If you need a specific mechanism, please request it from support from Cadence. We have validated mechanisms available for most technical fuels. If it is important to use a specific reaction mechanism, which we do not have in our data base, we might convert your mechanism from a Chemkin-format to a chem1d-native format. For what kind of fuel/oxidizer-combination do you need a mechanism?

Best regards

Excuse me, could you please send me a zip of chem1D? I have tried to download it from http://www. combustion.tue.nl/chem1d/, but it returns 404. Thanks a lot.

Dear Sir or Madam,

Which flow solver are you using? If you are using Cadence's tools (FINE/Open or Fidelity), I would suggest that you ask customer service for a license of TabGen/Chemistry. If you are an academic client, you might ask for an academic license.

TabGen/Chemistry applies Chem1d as a kernel, but unlike Chem1d it assembles and converts the flamelets for use in an industrial 3D CFD solver. TabGen/Chemistry can generate flamelets, flamelet libraries, equilibrium tables, tables for the hybrid BML/flamelet method, FGM tables based on premixed flamelets, FGM tables based on non-premixed flamelets. In addition, TabGen/Chemistry can generate non-adiabatic tables (heat gain and heat loss). TabGen/Chemistry is by default preintegrating (presumed beta-PDF) the combustion tables.

If you are not using Cadence's tools and you want to use Chem1d as a standalone tool, please contact Prof. Jeroen van Oijen of TU Eindhoven for access. Please note that a standalone version of Chem1d will not create you flamelet tables in the format, which Cadence applies. If you want to apply the tables of Chem1d in 3D CFD simulations, you will most likely need to write scripts for assembling the flamelets as well as a converter to the format your solver applies. Cadence will only provide you support on table generation matters if you apply Tabgen/Chemistry.

Best regards

Dear Sir/Madam,
Thank you. I just want to use Chem1d as a standalone tool. I read a Prof. Jeroen van Oijen's papers recently and want to calculate sensitivity coefficient mentioned in that paper. I will contact Prof. Jeroen van Oijen later if needed.
