Hello all,

I am thinking to start to have a try on the software FOAM from the OpenFOAM web.

I downloaded OpenFOAM-1.0.General.gtgz from Other platforms ( and also from Sun Ultrasparc Solaris )since I have only got access to a Sun Solaris workstation(32bit). Unfortunately, I failed to decompress the file.

I tried the following options: tar -xvf OpenFOAM-1.0.General.gtgz

This gives me the error massage: tar: directory checksum error

Then I try to follow the instructions given by the OpenFOAM web, I use: tar xzf OpenFOAM-1.0.General.gtgz

This gives the following error message: tar: z: unknown option

Could anybody out there tell me what mistake I have made or what I should do please ? Thank you very much in adavnce.

Yours sincerely,

Li

try renaming the file to OpenFOAM-1.0.General.tar.gz

then do "gunzip OpenFOAM-1.0.General.tar.gz"

then do "tar -xfv OpenFOAM-1.0.General.tar"

hope that helps

Jonas,

Thank you very much.

It does work better. However, a error message appears at a certain stage:

OpenFOAM-1.0/doc/Doxygen/html/d0/d14/cellDecompCuts_8H-source.html, 13860 bytes, 28 tape blocks

tar: directory checksum error

Now I have got two directories :

\bin

\doc

under \doc I can see three sub-directories:

\Allwmake

\Doxygen

\Guides-a4

But I cannot see any Fortran source file. Why?

Your help will be very much appreciated.

Download the file again from the openfoam website and try it.

That is strange. If the gunzip worked I would expect the tar to work also. A download error would break the gunzip not the tar. Perhaps your disk is full so that your tar file got truncated?

However, even if you untar succesfully, you'd never see any fortran in foam, as it is written in C++ ))

Is gnu tar available on (your) Solaris ? If yes, try running "gtar xzvf OpenFOAM-1.0.General.gtgz". The problem is perhaps due to a mismatch between tar versions.

Yup, you need gnu tar - the one from Solaris has got hard-coded max path length and the directory structure of foam is too deep for foam.

Using Fedora,latest, changed OpenFOAM-1.5.General.gtgz to.tar.gz and
did tar xzf - all went well.
Same thing with ThirdParty.General.gtgz no good
tried gunzip no good.

So this file is neither tar nor gzip.

Excuse fumbles, am new at this Linux, just need it for real work!
