Dear Tajoooko,

have a look at the following tutorial in 1.5-ext

$FOAM_TUT/tutorials/icoDyMFoam/movingConeTopo

Have a look here for how to obtain 1.5-ext

and other post on the forum.

Henrik

Dear Tajoooko,

you need 1.5-extend, not the 1.5 (plain, vanilla) or 1.5.x (patched vanilla, git) version, because what you want to do requires topological mesh changes.

Dear Tajoooko,

you are probably downloading the OpenFOAM on SLAX tar-ball which is a full operating system to put on a USB stick. It's probably not what you want, but it's very nice for beginners. Instructions are here:

OpenFOAM-dev Live USB CD, SLAX based

If you are aiming for the "normal" OF-1.5-ext installation. Follow the link in my first post. There is no binary pack, so you must compile from source.

No, put it into the drive and reboot, but make sure the boot order picks up the CD first.

then i unpake the tgtz of thirdparty and

do update my ~/.bashrc

then .$HOME/.bashrc

after that i do the installation test from openfaoam and every thing was ok

the icofoam solver and the blockMesh all was there (i just typ it in the bash)

after that i cd in the openfoam-1.5-dev and typ ./Allwmake this takes alout of time about 2 or 3 hours

and then every think was fisched

Dear Tajoooko,

Start a fresh shell and run foamInstallationTest. If it cannot be found, check your environment settings until you it's picked up.

The problem is here:

Dear Ammar,

sorry, but it seems to me that you are not taking advice and trying out alternative routes. I don't care if want to you waste your time, but I do object to wasting mine.

Please remove all those clever OF binary packages that make you life difficult. However, keep the vanilla OF 1.5 that you picked up from OpenCFD as a fall-back and in case you have trouble compiling paraFoam.

Go to the directory with the OpenFOAM-1.5 and ThirdParty directories (cd $FOAM_INST_DIR) and pull the latest OF-ext:
Code:
svn co 
https://openfoam-extend.svn.sourceforge.net/svnroot/openfoam-extend/trunk/Core/OpenFOAM-1.5-dev
Then pick this up with your environment, open a fresh shell, cd $FOAM_SRC, ./Allwmake, open another fresh shell, foamInstallationTest

@GCC: Anything > 4.2.0 will be fine as long it's compatible with your system.
