Hi
I'm simulating the specie transmission without any chemical reaction in the small office room.
But I get this error:
--> FOAM FATAL IO ERROR: (openfoam-2112 patch=220610)
Inert specie N2 not found in available species 0()

file: constant/thermophysical properties at line 20 to 119.

From reactingFoam
in file createFields.H at line 14.



The thermophysical properties file of this model is as fellow:

I would be very grateful if anyone could guide me to resolve this problem?

Suggest to check tutorials (Flame D?) on how inert species is defined.

cd system 
for ifile in `ls`; do echo $ifile; grep -i inert $ifile; done

Thank you for your reply,
I studied tutorials you mentioned, I also check the openfoam samples and write according those.But I still get this error that related to inert specie.

[dlahaye]

No clue.

Is N2 present as one of the species you wish to transport?

Should all reference to N2 in the case set-up be removed?

Yes, N2 is one of the species that wish to transport. Actually I want to simulate the CO2 concentration as a biomarker of virous from infected person in a small office room. N2, H2O and O2 are considered as air combination. there is no chemical reaction.
Should I consider all three species as the inert specie or I should just consider air and CO2 in this simulation and consider air as the inert specie?

Do you have in constant/combustionProperties the combustion switched off and in constant/reactionProperties the reactions switched off?

Yes, both combustion and reaction properties switched off.

Hello,

Which tutorials have you studied?
I'm not a reactingFoam user but the syntax of your file seems pretty different from the syntax used in reactingFoam tutorials.

Hello Yann,
Thank you for your reply.
Honestly, besides of some related papers I tried to check my model based on reacting foam sample of openfoam samples.
I would be very grateful if you could tell me the problem of this model or introduce me a good tutorial to read.
Bests,

It is important pay attention to the versions when looking for stuff online, as models and syntax may vary across the different OpenFOAM development branches and versions.

According to your error message, you seem to be using OpenFOAM-v2112, you can check the tutorials locally on your system: $FOAM_TUTORIALS/combustion/reactingFoam

Or online here: https://develop.openfoam.com/Develop...n/reactingFoam
