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: /*---------------------------------------------------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: v1912 | | \\ / A nd | Website: www.openfoam.com | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ Build : _f3950763fe-20191219 OPENFOAM=1912 Arch : "LSB;label=32;scalar=64" Exec : reactingTwoPhaseEulerFoam Date : May 20 2020 Time : 19:52:24 Host : LAPTOP-LTH2ON9V PID : 2578 I/O : uncollated Case : /mnt/c/Users/David/Downloads/OpenFOAM/OpenFOAM-v1912/RUN/fluidisedBed_REACTING_bcolumn nProcs : 1 trapFpe: Floating point exception trapping enabled (FOAM_SIGFPE). fileModificationChecking : Monitoring run-time modified files using timeStampMaster (fileModificationSkew 10) allowSystemOperations : Allowing user-supplied system call operations // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // Create time Create mesh for time = 0 PIMPLE: no residual control data found.

Maybe you can help with this issue. |

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 |
