Dear CFD-community,

i tried to simulate a reactive flow of fluids in OF230.
As a base i used the tutorial-case for reactingFoam and applied
several changes that would describe my problem.
The most important change is the main-Solver to rhoReactingFoam.
I'll post the log-file for further Informations about
the used thermophysical-, transport-, combustion-, etc. models.

The Problem in the set up case is a segmentation fault during the initialization
of the field. (see log-file)

I know that the first thing to check, in case of segmentation faults, is
the geometry and boundary conditions.
This i tested sucessfully with a methan-combustion in the reactingFoam tutorial-case.
But i don't want to exclude it as the root of the error by default.


I hope somebody can give me one or two hints, that could help solving the problem.
If any further Information is needed to get rid of the question tags, just ask.


Thanks

Tommy

Hello!
I use the rhoReactingFoam to solver a chemistry problem, the thermoType is samilar to yours.
I do not know why I can not run my case.I am confused.
Can you help you? Or you can upload your case.
Thanks you!

Greetings to all!

@Tommy Floessner: Sorry that no one was able to get to you on this topic. My guess is that there was a division by zero, possibly because the initial temperature for one of the fluids was set to 0 Kelvin. I say this because of these two lines of the output:
Code:
#1  Foam::sigFpe::sigHandler(int) in "/home/dread/OpenFOAM/OpenFOAM-2.3.0/platforms/linuxGccDPOpt/lib/libOpenFOAM.so"

#4  Foam::multiComponentMixture<Foam::polynomialTransport<Foam::species::thermo<Foam::hPolynomialThermo<Foam::icoPolynomial<Foam::specie, 8>, 8>, Foam::sensibleEnthalpy>, 8> >::correctMassFractions() in "/home/dread/OpenFOAM/OpenFOAM-2.3.0/platforms/linuxGccDPOpt/lib/libreactionThermophysicalModels.so"
The first line refers to the arithmetic problem, namely "sigFpe" refers to "signal Floating Point Error", i.e. a division by zero or attempting to calculate the logarithm of 0.
The second line indicates that the error occurred when updating/calculating/correcting the mass fractions.


@C_Cherry: Please provide the complete error message that you have gotten, the same way as Tommy did, because your error message might be similar, but could be due to an entirely different reason. Either way, my answer above might help.

Best regards,
Bruno

Thank you for your reply@wyldckat
In my case,the fluid flows in a pipe, the inlet temperature is 473K, the wall temperature is 873K, and the outlet is zeroGradient. The inlet pressure is zeroGradient, and the outlet pressure is 5MPa. The inlet velocity is 0.04244m/s, and the outlet velocity is zeroGradient.
I use the rhoReactingFoam to solve a chemistry problem.
I hope you can give me some help. I appreciate you very much!

Greetings C_Cherry,

My apologies, it's being nearly a year, and I never managed to find the time to look into the problem you were having. Hopefully you managed to solve the issue.

If you haven't, the crash seems to have occurred when it was trying to calculate the equation for C10H22, due to not being able to solve one of the polynomial expressions (resulted in an invalid floating point operation, hence the sigFpe)... not sure which polynomial it was exactly, if it was receiving pressure and returning temperature or vice-versa.

My guess is that the initial pressure inside the domain was set to 0, instead of 1 or 5 MPa, which would somewhat explain the sudden crash due to not being able to calculate things properly, e.g. using a very high pressure as one of the input variables into the polynomial, could not render a valid solution.

Best regards,
Bruno
