Dear all,


I just want to inform you that I moved the repository to github and rebuild the code for OpenFOAM 7.x.
https://github.com/shor-ty/CRECKFlameletModel

Hello Tobi,

Make/files are missing for all folders that are to be compiled. I reused the ones from your OpenFOAM 4.x version with some minor modifications and it seems to be working fine!
Thank you very much for still working on this. It is much appreciated.

Greetings,
azu037


Edit: You mention the ability to use the PIMPLE-algorithm for transient calculations in your description but I couldn't get it to work.The solver complains about missing the SIMPLE settings in fvSolution ...

[Tobi]

Ah I see, I will change it. If you do have it for any version please make a pull request.

Thanks.

PS: I am not working on the code anymore, I just keep it up-to-date for compatibility reasons.

[azu037]

It's really more than you can ask for, keeping it up to date!


I have a general question to all the people in the thread. I tried to get the transient solver to work with the SANDIA flame but I always encounter a sigFPE error. I tried different settings for the solvers, checked the BCs and schemes but to no avail. Sadly there is no transient tutorial case for the 2.3.x version to get a working example from but I tried settings from Hagen Müller's and Alberto Cuoci's transient tutorial case.


I'd be very grateful for some input or - even better - a working case to learn from.


Edit: I don't have a GitHub-Account but the changes from the 4.x version are minuscule. You just have to remove the folders src or flamelet in the paths of the files referenced in the Make/files

[Tobi]

Hi, the setup should be the same. The only thing that will change is the solver. I once had the transient solver added to the repository. Hmm ... maybe I should do it again.

I just saw that Hagen Müller made another derivation for the transient solver. The implementation to FOAM was also a bit different. He had hard coded something to the turbulence models which I did not like as it will destroy the original. However, if I remember correctly, he took some compressibility into account. So the solver derivation regarding the pressure equation was a bit different.

hi tobi
i try to compile following the instructions posted on github(https://github.com/shor-ty/CRECKFlam...e/OpenFOAM-4.x). but i get some errors " no matching function for call to..." what's wrong
i also get some "unused variable" warnings

Hi,

what I can tell you is the following:

1. A warning is just a warning, its fine
2. Based on your error, I don't believe that you did exactly what is given in the readme

flameletSimpleFoam.C:62:31: error: no matching function for call to ‘Foam::simpleControl::loop(Foam::Time&)’
while (simple.loop(runTime))
^

If you go to the source code of the OpenFOAM-4.x version (https://github.com/shor-ty/CRECKFlam...etSimpleFoam.C), you will see that the code in line 62 differs to the one in your error message. I guess you are still on the master branch rather than on the OpenFOAM-4.x branch.

git branch

This shows you on which branch you are looking at the moment. I would expect that it is not OpenFOAM-4.x. So please switch to the correct branch:

git checkout OpenFOAM-4.x

hi tobi
thanks for your help.
ps: the git link in compile instruction for OpenFOAM 4.x is out of date

[mikeYao]

hi tobi，
i downloaded kinetics from http://creckmodeling.chem.polimi.it/...1-c1-c3-ht-nox
and i try to interpret it into idealgas.bin and reactions.bin, using command:
./OpenSMOKE_CHEMKINInterpreter.sh --kinetics "kinetic(2003)/CRECK_2003_C1_C3_HT_NOX.cki" --thermo "kinetic(2003)/CRECK_2003_C1_C3_HT_NOX.ckt" --transport "kinetic(2003)/CRECK_2003_C1_C3_HT_NOX.trc" --output "OutputFolder"
but i got this message:
** Reading thermodynamic database...
Class: OpenSMOKE_CHEMKINInterpreter_ThermoData
Object:
Error: Expected: THERMO - Found:
Press a key to continue...
what does it mean?
regards,
mike

[Tobi]

As it is written. The program expects the word Thermo rather than -

[mikeYao]

hi tobi，
i don't understand where this - exists. i did not find it in .ckt thermo file.
and OpenSMOKE_CHEMKINInterpreter.sh is not written in human language. is there any other file need to look in?
regards,
mike

[Tobi]

The version you are using cannot handle "comments or whitespaces" and is restricted to the original format:

! This thermodynamic database was obtained by fitting the thermodynamic properties
! extracted from the following file: TOT2003.THERM
! The thermodynamic properties are fitted in order to preserve not only the 
! continuity of each function at the intermediate temperature, but also the  continuity
! of the derivatives, from the 1st to the 3rd order
! The intermediate temperatures are chosen in order to minimize the fitting error.
! Last update: 3/24/2020

THERMO ALL

Has to be changed to:

THERMO ALL
270.   1000.   3500. 
AR                      AR  1               G    200.00   3500.00  820.00      1

The first word in the file has to be THERMO without whitespaces or any other empty lines.

hi tobi,
does it mean that i can't use OpenSMOKE_CHEMKINInterpreter.sh to process .cki or .ckt or .trc file?
i got this message:
** Reading thermodynamic database...

what(): basic_string::substr
Aborted (core dumped)
regards,
mike

[Tobi]

As you might already realized, the interpreter as well as the kinetic applications are binaries and therefore, we cannot analyze the code. If you do have problems regarding the application you should ask the people from CRECK Modeling group. Personal, I never had the feeling they want to support people. My messages was only replied two/three times, so no chance. I signed for the openSMOKE application in order to see what they did new but I never got access. Thus, good luck.

Hello, wenxu

How can I use the LT utility to output a flamelet file with suffix .kg?

Many thanks!

[sante_junior]

hello to all of you
I managed to implement flameletSimpleFoam in OpenFOAM-4.0 and I have a problem; I can't run the default tutorial. The default mesh is not there.

Please I need the procedure to make this tutorial.

[Tobi]

Don't know why you built it for OpenFOAM-4 as I already have it here:

https://github.com/shor-ty/CRECKFlameletModel

Check it out. Things should work here with v4

[sante_junior]

Hello Mr TOBI
I don't understand what you are saying.
Please be more explicit!

Cordially !

[Tobi]

I said, that I don't understand why you implemented the flameletSImpleFoam into OpenFOAM-4. We have already everything in my repository. You simply can use it.

[sante_junior]

Hi Mr TOBI.
Indeed I used your repository and I followed the compilation procedure which worked well. The flameletSimpleFoam solver is present. But I can't launch the tutorial. That's why I'm having problems. I am a novice. Please I need your help.
