Error "elements not defined in..."
 

Please, could someone help me with explanation of this error:

Selecting chemistryReader foamChemistryReader
elements not defined in "/mnt/c/Users/David/downloads/OpenFOAM/OpenFOAM-v1912/RUN/fluidisedBed_REACTING/constant/reactions.air".

I have described the reactions.air file based on the bubbleColumnEvaporatingReacting tutorial which is inside RAS directory of a reactingTwoPhaseEulerFoam tutorials. The description is as follows:

species
(
NO
NH3
O2
N2
H2O
AIR
);

reactions
{
waterGasShift
{
type reversibleArrheniusReaction;

reaction "NO^4 + NH3^4 + O2^1 = N2^4 + H2O^6";

A 3.85e6;
beta 0;
Ta 0.6764e4;
}
}


I am trying to run the simulation using reactingTwoPhaseEulerFoam for a fluidised bed reactor. Although it names "reacting" There is no chemistry inside, so I am trying to add chemistry files from bubbleColumnEvaporatingReacting and change them according to my case.


Thank you in advance for any help.

Hi,

- Is there any chance for you to attach the `entire` log file, please, including the error?

Thanks for you reply.
Now I have passed through this problem and I have another problem the reason of which is not clear for me as well:

After that simulation is stopped.
Maybe you can help with this issue.

When I adjust the phaseProperties file in another way I got such king of error:

HI，Davyd
although i havnt see you constant/reactions.air flie

I think in this flie you havnt put element in first

like this ——





elements
(
O
C
H
N
);


species
(
O2
H2O
CH4
CO2
N2
);

reactions
{
methaneReaction
{
type irreversibleArrheniusReaction;
reaction "CH4 + 2O2 = CO2 + 2H2O";
A 5.2e16;
beta 0;
Ta 14906;
}
}
you can see how to define element in Openfoam web
mybe i am wrong ,

hahaha
