Hi,
Hmm.. It seems that OF-2.1.0 does not have nutkAtmRoughWallFunction boundary condition. So I have changed nut wall function from nutkAtmRoughWallFunction to nutkWallFunction in branches/2.1/CaseA case. Please see changeset below and exclude "svn update" in that directory! http://www.opencae.jp/changeset/128/OpenFOAM-VandV-SIG Masashi Quote:

I have made the changes, but log.Toposet has errors too.While log.sample has FOAM warning, hope this is okay.

There should be a 'topoSetDict' file in the 'system' directory, should it?

I could not resolve the problem using the above tips by Bruno. I did a ./Allrun in the kEpsilon folder and just to check out what is wrong with the script. Here is the error message during the simpleFoam run: /*---------------------------------------------------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: 2.1.1 | | \\ / A nd | Web: www.OpenFOAM.org | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ Build : 2.1.1-221db2718bbb Exec : simpleFoam Date : Oct 23 2013 Time : 14:19:00 Host : "judah-Ubuntu" PID : 23454 Case : /home/alex/OpenFOAM/CaseB-2.1/kEpsilon nProcs : 1 sigFpe : Enabling floating point exception trapping (FOAM_SIGFPE). fileModificationChecking : Monitoring run-time modified files using timeStampMaster allowSystemOperations : Disallowing user-supplied system call operations // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // Create time Create mesh for time = 0 --> FOAM FATAL ERROR: Cannot find file "points" in directory "polyMesh" in times 0 down to constant From function Time::findInstance(const fileName&, const word&, const IOobject::readOption, const word&) in file db/Time/findInstance.C at line 188.

Hi Alvin,

I have added topoSetDict in trunk repository but I forgot to add it in branches repository, sorry. So I just added it now. http://www.opencae.jp/changeset/129/OpenFOAM-VandV-SIG Masashi |

http://www.opencae.jp/changeset/130/OpenFOAM-VandV-SIG So please wait for a while until updating these cases for OF version 2.1.x. BTW as Bruno suggested, symbolic link files in CaseB/[RASModel] directories would not be checked out correctly if you check out on non *nix file system like NTFS or FAT. So checkout should be done on *nix file system or OS like Linux or Mac OS. All the Best, Masashi |

Hi Masashi-san,
1) I would like to ask about your case A on the site http://www.opencae.jp/wiki/OpenFOAM-VandV-SIG/AIJ-PWEAB I looked through the '0' folder and it uses 'timevaryingmappedfixedvalue'. I thought you have used setdiscretefield utility since this case A does not use snappyhexmesh. Am I right to say that even for discretesetfield utility, one needs to specify the timevaryingmappedfixedvalue BC in the 0 folder? 2) Since you have done the case A using timevaryingmappedfixedvalue and setdiscretefield, is there any difference in the final results obtained? Regards Alvin |

Dear Imano san,
I am wondering have you ever compiled the AIJ validation results obtained using OpenFoam? If yes, could i have the privilege to obtain a copy of this report ? The purpose of this request is to enable me to bring to our building construction authority (BCA) and to convice them that OpenFoam results are as good as Fluent or CFX or Star CCM. Currently, they are so stiff neck about their decision on not letting people submitting OpenFoam results in building performance analysis submission. Your help is very much appreciated. Thank you. ALEX LEE |
