Greetings all! OpenFOAM 1.4
 

Greetings all!

OpenFOAM 1.4 basis is successfully ported on Windows(tm)/Cygwin platform. You can download whole port from OpenFOAM Extensions project, tab Downloads, hosted on SourceForge.net. Check this website for future Cygwin port releases.

Package OpenFOAM-1.4-1.cygwin.src.tar.bz2 is a source distribution that compiles without problems under Cygwin. It is a case-insensitive distribution, you can directly unpack it onto Windows file system. Read carefully a README.Cygwin before you start, please. I won't support anybody who has problems 'cause of his inability to read that file.

Package gcc-4.1.2-cygwin.i686.tar.bz2 contains binaries of a GNU GCC compiler, that is compiled with all necessary configuration switches. Do not use GNU GCC distributed with Cygwin, your OpenFOAM won't work with it.

Unported futures at this very moment are FoamX, patchTool and parallel stuff. Further porting work is in progress and concentrates exactly on the missing futures.

Your feedback and bug reports are welcome.

With best regards,
PV

Thanks for a great work!

When I tried building the port on a 1 GBytes machine, linking libfiniteVolume.dll failed due to, guess what, out of memory. Observation with the task manager after allocating 2 GBytes (it was a VM on Linux) revealed the process to take about 820 MBytes, so those who try building the beast might want to have enough RAM space.

Other than that compilation seems to have finished without noticable trouble. Again, thanks for an impressive porting work.

Greetings!

I am not sure if it is normal to make a new release 2 days after 1st one, but well, things happens.

Therefore, I proudly announce new Cygwin port release OpenFOAM-1.4-2.cygwin.src.tar.gz, you can download from OpenFOAM Extensions project.

What is so new to make it up for a new release? Parallelization and tons of small scripts shavings and polishes! You are getting historically the first Cygwin port that is coming with parallel computations based on LAM/MPI. I successfully ran a tutorial example damBreak balanced on 2 processors of my old good Intel Pentium CPU with HyperThreading under Windows. And no, I am not going to make screenshots for you, do them yourself.

Port compiles, straight of package, into a non-parallel version, you have to just uncomment WM_MPLIB variable in bashrc file. Rest is a cake as usual.

Nice Weekend!

PS: You who are unsure what Windows/Cygwin is and if it is good for you, visit Cygwin Website first, please.
PS2: For those who cannot get README.Cygwin out of an archive to read it, here it is attached for you. You can as well use bunzip2 followed by tar to unpack it yourself.

Hi Petr and OpenFOAM extension
 

Hi Petr and OpenFOAM extensions people,

Now that I finished the porting work of FoamX/patchTool/"paraFoam via native reader" over the OpenFOAM-1.4-2.cygwin release, I'm attaching the patch. I think it'd be nice if the patch is included in the cygwin port distribution.

In fact, this time Petr and I have agreed beforehand to include FoamX-patch in the Cygwin port of OpenFOAM upon completion, so I sent the patch to Petr twice but currently I have no response. Could anyone in OpenFOAM extensions project contact him?

Of course anyone who's intersted in the patch can try it, and I'd be glad to hear how it works or not.

Note:
1. Before applying the patch you need to pull mico-2.3.12 distribution from the official OpenFOAM-1.4 source tarball or from MICO website http://www.mico.org and place it under OpenFOAM-1.4/src.

2. There's not so much to mention technically because the patch basically carries over the work from 1.3. One exception, however, is that now you don't have to set JAVA_HOME manually - the initialization script looks for the newest JDK under the %PROGRAMFILES%\Java directory (usually C:\Program Files\Java).

Hi,

Here's another patch again for OpenFOAM-1.4-2.cygwin. This is a collection of fixes for whatever I noticed while using but not related to FoamX-stuff.

The patch includes
* fix to ccm26ToFoam building problem
* fix to libphaseModel building problem
* porting of some of the scripts under OpenFOAM-1.4/bin (foamInstallationTest etc.)
* slight modifications to Pstream/Allwmake and wmake/makeWmake
* modification to .so loader (dlLibraryTable.C) so that .dll files can be loaded even if a file with .so extension is specified
* workaround for kivaToFoam crash
* dieselFoam/aachenBomb problem reported here.

Greetings!

I am sorry it took so long, but my holidays, illness, me being busy and week problems to get the last release up on the SourceForge.net delayed whole long anticipated Cygwin port. Thanks to Takuya Oshima we got now even FoamX and paraFoam working and with that we got all features running on Windows/Cygwin platform. You can download last release OpenFOAM-1.4-3.cygwin.src.tar.bz2 as usual from OpenFOAM Extensions project.

Regarding the release of OpenFOAM 1.4.1, I am skeptic we will port it any soon. Hm. I hope Bernhard won't kick me into it.

Have your fun!

Wow, I just arrived here at OpenFOAM and I am impressed with the effort just in this thread!

This port is ideal for me so I will try to install it soon. One question. How will this work on an Intel Core Duo processor? Will this need to use the parallelisation feature to get the most form it?

Hello!

I would like to know if these cygwin ports will do the job submitted from a linux distro under parallel mode .... ?

I am having some issues with Cygwin trying to install OpenFOAM. I am new to Cygwin and not an expert in Linux.

1st. When I run bashrc I get a message saying

ls: cannot access jgk*: No such file or directory

I set the ALT_UNIXCOMMAND_PATH to my jdk directory and I still get the message.

I tried to run Allwmake anyway and it produced a large number of errors such as these.

+ cd wmake
+ ./makeWmake
Makefile:61: /rules//general: No such file or directory
Makefile:62: /rules: No such file or directory
make: *** No rule to make target `/rules'. Stop.

+ wmake libso zlib-1.2.1
./Allwmake: line 6: wmake: command not found
+ wmake libso foamUser
./Allwmake: line 7: wmake: command not found

I have installed OpenFOAM in the following directory

/home/David/OpenFOAM/OpenFOAM-1.4.

The jdk is installed in the C:\Program Files\Java\jrockit-R27.3.1-jdk1.6.0_01 directory.

As far as I can work out i have installed all of the additional modules required for OpenFOAM as per the Readme. In additon there were some modules recommended for java that I added.

Any help would be appreciated.

Hi David, @JDK installation:
 

Hi David,
@JDK installation: in your case you have to set JAVA_HOME to your JDK installation directory manually by editing the line 175 of ~/OpenFOAM/OpenFOAM-1.4/.bashrc, as written in README.Cygwin.

@Allwmake problem: you have to run source ~/OpenFOAM/OpenFOAM-1.4/.OpenFOAM-1.4/bashrc before running ./Allwmake.

Takuya

Takuya, Thanks for the help
 

Takuya,

Thanks for the help. I don't see anything in the README about editing line 175. I had made JAVA_HOME = ..jdk.. a windows envirnonment variable.

I still get the "ls: cannot access jdk*: No such file or directory" message now.

Does anyone know if running OpenFOAM with cygwin would be better or worse than installing vmware and running it under linux?

Hi David, @ls message: If you
 

Hi David,
@ls message: If you do maind the harmless warning just comment out that part of code (lines 159-168). And if I'm allowed to say a bit more, the Cygwin port as a whole is for those who have enough expertise as to be able to determine what to do by yourself, or at least with a hint in README.Cygwin: "2.1. Usually the OpenFOAM initialization script (OpenFOAM-1.4/.bashrc) automatically looks for the newest version of installed JDK. If it doesn't work set JAVA_HOME variable in OpenFOAM-1.4/.bashrc manually after unpacking the OpenFOAM distribution."

@VMware: I think it totally depends on what expertise you have and how you plan to use OpenFOAM. As for me, I have both OpenFOAM+Linux on VMware and the Cygwin port but the one I regurally use is the Cygwin port.

Takuya

It is nice to know that the message is harmless.

OpenFOAM has been compiling for an hour or 2 so far without anything that appears to be a major error message.

FYI I was reading the README from the link above and the section 2.1 in it is different.
Also, if people never go outside their comfort zone, they never learn anything.

I tried to install version 1.4.3 of openFoam 1.4 cygwin following the README.Cygwin and the information posted on this thread.

Hi Luca,
Hmm, extrapolating the seemingly truncated error message it is likely that the FoamX-stuff didn't actually compile. Could you

Takuya,
thank you very much for your help.
I was finally able to run foamx. Here is what I did:
I figured out that inetd wasn't working properly on my machine so no rsh and no foamx! I had inetd reinstalled, reconfigured the /etc files by running iu-config, edited the /etc/passwd file and finally re-installed the service following
http://www.mail-archive.com/cygwin@cygwin.com/msg81912.html

Then I reran the make install in
mico-2.3.12/platforms/cygwinGcc4DPOpt/include
following your instructions and recompiled foamx by running ./Allwmake in
~/openFoam/OpenFOAM-1.4/applications/utilities/preProcessing/FoamX
at this point I had it working... or at least the application window appeared.

By the way, during my wanderings I also figured out that the ping test performed in foamInstallationTest doesn't work on cygwing installation based on non-english operating system since it tests for a "received" substring in the response. Also the rsh and ssh tests use a telnet on port 22 and 222 that did not work on my machine even though rsh is actually working fine.

Hope this might help somebody else.

OK those who would like to run the ping test with foamInstallationTest under a non-English environment might want to try this patch http://www.cfd-online.com/OpenFOAM_D...hment_icon.gif foamInstallationTest.diff after installing Cygwin's ping by its setup.exe.

To be honest I ported foamInstallationTest rather for fun and never thought of its serious usage http://www.cfd-online.com/OpenFOAM_D...lipart/sad.gif.

Now I would like to mention that I started some preparatory studies on porting OpenFOAM to Interix, also konwn as SFU (Windows Services for Unix) or SUA (Subsystem for Unix-based Applications). The reasons I'm attracted to Interix are

• Interix performs a lot better in I/O operations,
• The interix I/O subsystem postulates to be set up as case sensitive (I know Cygwin also support case sensitive file handling through managed mount but it's not a usual custom),
• Interix is Microsoft's genuine unix-like environment, which might be important to institutional users.

As of now I'm in a stage that I just barely bootstrapped gcc-4.2.2 on Interix, whose C++ and Fortran parts turned out to be mostly broken. I will open another thread regarding this project with some detailed discussions, if I can get GCC to reasonably work.

Dear Cygwin users, I've rec
 

Dear Cygwin users,

I've recently installed OpenFOAM-1.4-3.cygwin and I wanted to try setting up a cluster of Windows PCs. Despite a few attempts I couldn't run any parallel case using LAM/MPI, and the lam system itself seemed to me not very stable.
In fact, I tried running a few of the simple examples provided with the LAM/MPI distribution and, although they worked, the lam net was crashing after launching the same code a few (2 or 3) times consecutively (i.e. without lamwiping and lambooting again each time). As far as OpenFOAM is concerned, the parallel case was starting but crashing at the first time step.

I absolutely don't mean that LAM/MPI or the OpenFOAM+LAM distribution do not work, but that I probably made some mistakes during the installation which I couldn't correct and solve.

Thus, I looked around and decided to try MPICH2.
I downloaded the source of the latest UNIX distribution (mpich2-1.0.6p1), compiled and installed it on Cygwin straightforward, run the same few example (never crashing now!) and then turned to make OpenFOAM working with MPICH2.

After a few attempts it seems that I now managed to correct all the few scripts (bashrc, Allwmake and options files) which need changes for the OpenFOAM Cygwin distribution to (optionally) compile and run with MPICH2 and I'm now running a few small cases on my cluster. Very happy, indeed !!
I'll try to understand things a bit better and later report about the performances obtained.

In case anybody (Petr, Takuya ?) would like, I could provide the patched files to allow choosing either a LAM or MPICH2 installation.
I still have to look at the FoamX stuff however.

Luca

Hi Luca,
Although I myself usually don't do parallel runs it would be so nice if you post your patch here since the quality of the Windows port is always my concern, and most of all, it will help others who may be silently giving up running the Cygwin version in parallel without leaving any messages here...

As to the FoamX-stuff, as usually suggested in this forum I also suggest you learn how to get your jobs done without FoamX rather than wasting your time getting FoamX to work... although reading your posts it must already have been quite a lot of investment in time to you.

Takuya

Greetings Luca!

Dear All,

I spent a little more time to better check the MPICH2 package and test some of its compile options: I'm now happy with it and I've been running parallel processes on 1, 2 or 4 PCs (either P4 Hyperthreading or Dual Core).

I'll report in a different post about the results but it seems that even on one single PC it might be worth running a parallel job with 2-4 process: this way I've got up to 30% improvement on both P4 and Dual Core (for 0.5M cells).

Attached here is a tar with all the patched files and a readme with installation instructions and a few comments.

Happy parallel computing !

Luca

Hello, I'm having trouble g
 

Hello,

I'm having trouble getting FoamX and paraFoam to run. I've run out of ideas so I'm hoping you could help me.

As far as I can tell there are a couple of things going wrong with the build:
1) Allwmake under OpenFOAM-1.4/src/malloc is not compiling properly. The error is:
fbsdmalloc.c:866: error: 'MADV_DONTNEED' undeclared (first use in this function)

2) later on mico-2.3.12 is not compiling. The configuration log lists a couple of definition files missing and only the first two libraries are being compiled. The third one exits with an error.

3) None of the FoamX binaries have been compiled and I'm guessing that it's because of this as well.

rsh works fine on my machine.
The solvers and blockmesh also work well. (I really appreciate this port since I do my cad work on Win and switching between OS's is not fun http://www.cfd-online.com/OpenFOAM_D...part/happy.gif)

All of this is on WinXP with a 686 processor.
OpenFOAM-1.4-3.cygwin.src.tar.bz2
gcc-4.1.2-cygwin.i686.tar.bz2
JAVA JDK 1.6.0_03
Cygwin 1.5.24-2

Any idea on what could be going wrong or how to check?
Thanks,
Erez

Hi Erez, 1) It's a bit strang
 

Hi Erez,
1) It's a bit strange that src/malloc/Allwmake is being run since in src/Allwmake the corresponding line is commented out by an if-clause.
if ! [ "$WM_ARCH" = "cygwin" ]
then
(cd malloc ; ./Allwmake)
fi
Maybe WM_ARCH is not set properly?

2) I might (or might not) be able to give some suggestions if you post the log here.

3) Your guess is right, the FoamX binaries will not be built unless the MICO library is built.

Takuya

Hi Takuya,

My bad. Didn't see that ! sign http://www.cfd-online.com/OpenFOAM_D...part/happy.gif
That of course would explain why I couldn't compile it. (I tried to compile it myself)

But still I can't compile MICO.

Here's the error I get after running make:
../include/mico/os-misc.h:286: error: declaration of C function 'int gettimeofday(timeval*, timezone*)' conflicts with /usr/include/sys/time.h:73: error: previous declaration 'int gettimeofday(timeval*, void*)' here
make[1]: *** [os-unix.o] Error 1
make: *** [system] Error 1

Would it be possible to lift these libraries from another build? Either from a linux distro build of OpenFOAM or from the binaries of the 1.3 Cygwin build?

Thanks,
Erez

Hi,
Although I have never tried, the 1.3 FoamX binaries might work with 1.4. The binaries can be downloaded from here.
Note that the binary distribution doesn't contain the MICO libraries since they are statically linked into the FoamX binaries.
