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!

Dear Masashi-san,

I have changed to OF2.1 and included the boundaryData's points, k, U and epsilon in the constant folder.
All the log files did not show up any error messages, except 'log' file.

Thanks a lot.

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?

Greetings to all!

Looking back at the original problem:

The problem is that this "link" is actually an artificial link created by the SVN mechanism. It actually means that when checking out the source code through SVN, it would automatically interpret the "Allrun" file as a symbolic link pointing to "../share/Allrun", namely this file: http://www.opencae.jp/svn/OpenFOAM-V...B/share/Allrun

To manually fix this, run from the "CaseB" folder the following block of code on the command line:

Code:

for model in kEpsilon NonlinearKEShih RNGkEpsilon realizableKE

do

    cd $model

    rm Allrun

    ln -s ../share/Allrun Allrun

done

And that's that! It's ready to be used.

Best regards,
Bruno

Dear all,

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:

Right!
I have added topoSetDict in trunk repository but I forgot to add
it in branches repository, sorry. So I just added it now.

I just removed branches/2.1/Case[B-F] for maintenance.

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

ありがとう, Masashi san

Hi Imano san,

Not sure if there is any update of the cases?

updates on cases on maintenance

Hi Masahi, any updates for any of the case taken down for maintenance soon?

comparing timevaryingmappedfixedvalue and setdiscretefield

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

AIJ Test Cases OpenFoam Report

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
