I have just run the dieselFoam tutorial case with OpenFOAM-1.1 and it ran fine.

[adorean]

Hi,

Now I have installed OpenFOAM-1.1 and I still got the same problems of missing entries in the dieselFOAM - aachenBomb case as in 1.0.2.

I have installed OpenFOAM-1.1 as it sais on the web page and readme.

When opening FoamX get these errors:

Non-optional dictionary entry 'runTimeModifiable' not found in dictionary
/home/ervin/OpenFOAM/ervin-1.0.2/run/tutorials/dieselFoam/aachenBomb/system/cont rolDict

in file /home/ervin/OpenFOAM/ervin-1.0.2/run/tutorials/dieselFoam/aachenBomb/system/fvSc hemes::divSchemes
start at line 38 ending at line 51

... etc.

How is it possible? What am I doing wrong?

Thank for your help

The aachenBomb tutorial has not been corrected for FoamX although it does run fine, try the Allrun script to check it on your machine.

The problems with this tutorial and FoamX have been reported before and I was told I would receive a set of correction for it but they have not been posted to my knowledge and hence not included in the 1.1 release. As soon as I receive the corrected files I will include them for the next release.

[adorean]

Hello Henry,

It's running.
Thanks for this tip. Now I understand.
The one who said that will correct this case for FoamX was me, but I couldn't finish it yet.

So, one more question:
If the case is running correctly from the command line it means that the entries in these tutorial files are correct and the FoamX configuration file needs to be modified? Which one is it?

Thank you

Ervin

[henry]

FoamX show there are missing entries in the tutorial files as indicated by the error messages but the code can still run because these entries are optional and default values are assumed if they are not present. FoamX does not currently have a concept of optional entries in dictionaries and so they must be complete. Unfortunately this tutorial was created by someone who does not use FoamX (you can own-up if your want to, we know who you are...) and all the dictionaries were written by hand starting from an existing case and so no checking was done to make sure it was compatible with FoamX.

Now that we have a large number of users I hope these error will be found and corrected quickly for the benefit of all future users.

[adorean]

Or, if the case has to be corrected, than I was adding the missing entries in the dictionary files of the case, but I don't know the values for some. For example: ft, fu, A.

Thanks

[adorean]

OK.

Thanks

Ervin

[henry]

OK, I will take a look at it later and post the necessary changes.

[henry]

The current FoamX configuration files for dieselFoam correspond to a very old version which used a very simple combustion model. The new dieselFoam supplied by Niklas Nordin user his multicomponent mixture spray model and a combustion model including complex chemistry. Unfortunately no one has had the time to update the FoamX configuration files for these developments and it looks like a substantial effort because not even the current spray modelling has up-to-date FoamX support. So unless you are someone else has the time to spend on the task of updating the FoamX configuration files users of dieselFoam will have to edit the contol dictionaries by hand at least for now.

Hi Guys

I need a help. I'm testing the dieselFoam solver with the aachenBomb tutorial case and I have problems trying to restart it. If I put to run with the controldict such that:

startFrom firstTime;

I have not problem and the case runs. But when I put the case to restart using, for example:

startFrom startTime;

startTime 5e-05;

The solver crashes and the following message apears in the output.

==========================================

I tested using either binary as ascii writeformat and both does not work. Could somebody help me?

Many tanks in advance

hi!
I am running the aachen bomb tutorial. the Time is now 0.015 and the CO2 file in time directories(eg 0.0149) shows nothing. I think there is no reaction in this case(is it right?). only a reduction in temperature(caused by evaporation)
thank you for your time

sorry
it works
the chemistry was off
sorry

[gschaider]

Did anyone manage to post-process the spray-particles when working with the 1.2 version? When running dieselFoam v1.2 on the aachenBomb tutorial the only file that is written to the lagrangian-subDirectories of the time directories is positions. When running v1.1 on the same case (fvSchemes had to be replaced) a lot more files get written (T, U etc).

If there is only a positions-file foamToVTK doesn'T create any data for the particles (which is OK, because the positions alone are not very interesting). Without that data they can't be visualized (of course)

Is this non-creation of files a problem of

* the lagrangian code in the library
* dieselFoam itself
* wrong configuration in the tutorial

[mattijs]

There should be no difference between 1.1 lagrangian data and 1.2. So it still should write mulitple files to the lagrangian/ directory.

Sounds like the tutorial configuration is different.

Can you figure out what is going wrong and send an update?

[gschaider]

I didn't stress that enough in my first posting: I ran the v1.1-dieselFoam on the v1.2-case (I just replaced the fvSchemes-file with the one from the v1.1-tutorial) and it worked.

I compared the two tutorials anyway and the only significant change seems to be in thermophysicalProperties: burntProducts1 and stoechiometricAirFuelMassRatio1 were removed
(but as the v1.1-solver has no problem with that I think it wasn't important in v1.1)

[gschaider]

I compared the diesel(Engine)Foam-solver code too. I didn't find any changes there that I would blame for that problem.

I then compared the src/lagrangian-files from the 1.1 and the 1.2 distribution and stumbled upon the following thing in parcelIO.C (apart from that I didn't find any changes of interest for that particular problem):

The Cloud<parcel>::readFields() and Cloud<parcel>::writeFields() (which seem to be in charge of outputing the missing fields) are marked as template specialisations (with template<>) in the new release.

Could this be the problem?

[mattijs]

Should not be a problem. Is just for some compilers' sake.

Have you tried putting some Info statements in there to see if they get called? Or compile with debug and run through ddd/gdb and sprinkle some breakpoints around.
