Hi,
When I open the case aachenBomb of dieselFoam I get these error messages in FoamX. Can anybody tell me what they mean or where are these parameters described? The case aachenBomb I've copied in my run directory just as I found it in the OpenFOAM tutorial directory. Ervin Successfully connected to name service.

If I were you, I'd give up on FoamX and run the case from the command line. It looks like either the FoamX config files are out of date and inconsistent with the updated case or the case itself is out of date.
Have a look at various dictionaries using the editor and try running the case from the command line - it will do most of the things FoamX does for you (and give you some more freedom). Alternatively, you can add: runTimeModifiable yes; into system/controlDict and carry on doing that with all other missing entries (read the error messages, they are pretty good!). Have in mind that the code still needs to work, ie. the FoamX config files are not necessarily correct. Enjoy, Hrv |

Despite Hrvoje Jasak's dislike for FoamX it remains a good and useful tool for many OpenFOAM users and we plan to continue to develop and support it with help from users (obviously not including Hrvoje). Once you have added the missing entries from the dictionaries in the aachenBomb test case please send them back to us and we will include them in future releases for the benefit of other users who wish to continue to use FoamX.

Hello Henry,
I don't think this was called for - I only said what I would do. While FoamX may do quite a lot and is reasonably good for novice users, it will never be able to do all I want and some things are just way too inconvenient. For example, consider typing in a mesh description for a 20-block mesh using FoamX. For this reason, commercial CFD codes provide a scripted interface - if Foam, one can simply edit the files by hand or script-change them. As for my work on Foam, bug fixes and development, I will let my record speak for itself. The new tutorials and top-level solvers come not only from my work but also from my students, with the hope they will be useful and without strings attached.

I do not know what this refers to or how to respond. 1.1 will be release without any such contributions because none were submitted. |

Two reasons:
1) On top of all files in OpenFOAM it says: Copyright (C) 1991-2004 OpenCFD Ltd. I am not sure how I feel having a statement like this on my work. Maybe it's OK, maybe it's not, maybe I just need time to get used to it. 2) The deal (of 3 days ago) is that I wait for the beta release and merge my things into it and then pass on the changes and the beat is not out yet. For the record, thenew things are as follows: - reimplementation of parts of the finite area solver - automatic mesh motion has been re-packed and now comes with run-time selection of governing equations and distance and distortion-based diffusivity - free surface tracking solver is ready - see my recent presentations. It will be released with two tutorials, free surface tracking for waves and a free-rising bubble with surface tracking and surfactant effects. - numerous bug fixes in topological changes, especially for layer addition/removal and sliding interfaces. The engine valve motion work is still in progress and will nto be released at this stage. Please note that the config files for specifying layering, sliding and other topological changes has been changes to allow multiple topo changes within a single time-step. On the documentation side, there is a new PhD Thesis by my student Dr. Zeljko Tukovic describing the automatic mesh motion solver, its implementation and use. It is currently being translated to English. Best regards, Hrv |

Incidentally, a public CVS repository and a developer's public forum of the kind "this is what I'm thinking, these are the consequences, let's do some development together" would do a lot to alleviate my concerns.
I think a public CVS should be considered if possible in the nearest future. Hrv |

Thank you both for your swift replies!
1) I will do that Hrvoje. If I run into trouble I will ask for help. 2) I'll try to fix the aachenBomb case, Henry and make it running. When I'll do that I'll send it to you. My interest in OpenFOAM is almost exclusively concerning it's possibilities to model diesel spray and combustion. I have started my PhD with Fluent, continued with Kiva-3v, and it looks like I will finish it, delayed, but hopefully with much more satisfaction with OpenFOAM. So, I kindly ask all the OpenFOAM team to let me know how can I get hold of articles where the theory regarding diesel spray and combustion (implemented in OpenFOAM) is described. The "ftp://monet.me.ic.ac.uk/pub/papers/TF9307.ps.gz" doesn't work. Thank you. Ervin |

OpenCFD was setup to enforce the GNU GPL on alll the OpenFOAM releases to protect all contributors including you.

Hrv,
OpenCFD plans to continue to develop OpenFOAM as well as collate, merge and test contributions. If you would rather setup a CVS repository for your developments you are free to do so, as is anyone else; OpenFOAM is a GPL product and anyone can use it or develop it in any way they like as long as they work within the constraints of the GPL. |

Ervin,
I think the best reference text for the spray and diesel combustion in OpenFOAM is Niklas Nordin's thesis -- right Niklas? TF9307 covers the development of my premixed combustion model, the more generalised version of which is implemented in XiFoam, engineFoam and Xoodels. |

I have now Niklas Nordin's thesis. Can you please tell me how to get hold of TF9307. Or can you please send it to me? I'm also interested in it's later development. Above, I meant that the ftp address doesn't work. My e-mail: eadorean@yahoo.com Thanks Ervin |

Hi,
I would just like to say that I used mainly 2 theses as reference when I implemented the spray stuff and they are C. Kralj, Numerical Simulation of Diesel Spray Processes D. Clerides, Numerical Simulation of Spray Processes in Diesel Engines I have them both as ps-files but I dont know if I am allowed to distribute them. Niklas |
