I need a few pointers for a beginner in this field. I am interested in simulating wind fields in the proximity of buildings. I would like to use OpenFOAM for windows under Cygwin. Where can I find step by step beginners instructions for the installation of the software. Where can I
find information regarding the use of OpenFOAM in
this type of application?

Hi again Takuya,

Just tried using the FoamX binaries from 1.3. Sorry to say that they didn't work. Guess I'm back to trying to compile mico.

How do I upload the log file?

Thanks,
Erez

Hi,

Got it to work finally

I modified the line that was causing the error:
In OpenFOAM-1.4/src/mico-2.3.12/include/mico/os-misc.h
On line 286
I changed
extern "C" int gettimeofday (struct timeval *, struct timezone *);
to
extern "C" int gettimeofday (struct timeval *, void*);

Rerun ./Allmake and now everything is working great!

Again, thanks for the port... Now onto parallel processing! :D

Hi Cygwin/Windows users,

A Windows binary package is prepared for ParaView 3.3-CVS snapshot with the OpenFOAM reader I posted on 23/Oct/2007. You can download from: http://oshima.eng.niigata-u.ac.jp/OpenFOAM/ParaView/

Have a look at the documentation page on the Wiki first, unpack the zip and install into any suitable directory (typically C:\Program Files\ParaView). By adjusting the line 50 of ~/OpenFOAM/OpenFOAM-1.4/.OpenFOAM-1.4/apps/paraview/bashrc in your Cygwin port installation which reads

export ParaView_INST_DIR="/cygdrive/c/Program Files/ParaView 2.6"

to point to the directory where you installed ParaView 3.3, you can load cases into ParaView with paraFoam (since the paraFoam script in Cygwin port is made to use a native reader).

Have nice holidays,
Takuya

All Cygwin users/Takuya,

I have big troubles with compiling and running FoamX. Everything looks fine excepting the mico-2.3.12, there is a lot of errors and warnings. Can you help me with this.

Thanks,

Josef

Hi Josef,
As can be seen from all the posts above, getting FoamX to work seems to require a bit subtle task... I'm not sure if I can be of any help to you since I somehow almost never gone through a trouble, but could you post the error messages first?

Hi Josef,
Looks like you're having the same problem Erez Raviv reported by the post above on Tuesday, December 18, 2007. Try the fix he suggested.

I have a relatively low end machine. It has been 24Hrs+ since I started to compile the beast in a XP machine and still compiling and it took a lot of time in libfiniteVolume.dll.

Is it normal?

Dear all,

I am having trouble to install OpenFoam in cygwin. After run bashrc without any problem, I am keeping geting this error code 127 while running Allwmake. It seems like problem can not find the right file.

I went to back to the wmake folder and can not find /wmake/shScripts folder. There is only folder named bashScripts there. I don't know what causes the problem. Can anyone give me some guidance here. Thanks for your help.
Btw, my computer has Vista OS.

Hi Quinn Tian,
I guess you're using /bin/sh as your console shell, or at least somehow the SHELL variable is set to /bin/sh. Use /bin/bash instead, or set the SHELL variable to /bin/bash before sourcing ~/OpenFOAM/OpenFOAM-1.4/.OpenFOAM-1.4/bashrc.

Takuya,

Thanks for your reply. You suggestion works for me. But now I am having another problem with file cpp.exe and as.exe, after I start Allwmake. Please see the information beblow. Any comments? Thanks again for your help.

Hi Takuya

My name is Emiliano, I new user in the cygwin environment, I install cygwin and OpenFOAM in my computer. but I have problem to use paraFoam, I don´t understand the procedure to install mico and patch FoamX-cygwin-20070723.diff.gz, I download patch FoamX-cygwin-20070723.diff.gz and unpack on OpenFoam/src

You can send procedure step to step, to install and run mico an patch paraFoam, all the command to use, for execute all installation

My OS is XPhome

Hi Lucas or takuya

I have the same problem taht you my OS this spanish and does not work the FoamX but and don´t understand when you say reconfigured the /etc files by running iu-config, edited the /etc/passwd file and finally re-installed the service following

you can help me

[austricliniano]

Luca or Takuya

the problem is when I tray to use FoamX, the computer send the next message:
emiliano@CasaDoris ~/OpenFOAM/emiliano1.4/run/tutorials/potentialFOM$ FoamX
Starting NameServer with inet:CasaDoris:1234 ...
/home/emiliano/OpenFOAM/OpenFOAM-1.4/bin/runFoamXHB: line 144: nsd: command not
found

and standby along time, without doing nothing

Any hints on how to solve the problem?

[7islands]

Hi Emiliano,
One likely cause is mico wasn't compiled correctly. Check if nsd exists in OpenFOAM-1.4/src/mico-2.3.12/platforms/cygwinGccDPOpt/bin (or somewhere around there) and if it doesn't exist, try the fix in Erez Raviv's post on Tuesday, December 18, 2007.

Hi,

Not related though to cygwin port of OF, but this migth help others who would like to run OF on Windows(TM) OS.
Last week I was able to run OF on andLinux(Ubuntu Gutsy). OF seems to run correctly including FoamX with only problem in some needed library like libXp.so.6, libelf.so, and Xorg + change localhost in /etc/hosts to anything (I use andLinux) and comment the next two lines there.

The speed is good but I can not compare with the cygwin port since I was not able to succeed installing the cygwin port of OF.

Paraview runs rigth out of the box but it is not showing the graphics area. It is just grayed out.

So I installed the windows base of Paraview and use foamToVTK to view result.

Any thoughts on the paraview not showing the graphics area? Do I need more libs?

Thank you

Hi,

I'm trying to install the latest cygwin release. However I have some problems.

When executing the bashrc in a cygwin prompt I get the following:

KSK@PC-9862 ~/openfoam/openfoam-1.4/.openfoam-1.4
$ . bashrc
+ . bashrc
++ $'\r'
bash: $'\r': command not found
++ export $'WM_PROJECT=OpenFOAM\r'
++ WM_PROJECT=$'OpenFOAM\r'
++ export $'WM_PROJECT_VERSION=1.4\r'
++ WM_PROJECT_VERSION=$'1.4\r'
++ export $'WM_PROJECT_LANGUAGE=c++\r'
++ WM_PROJECT_LANGUAGE=$'c++\r'
++ $'\r'
bash: $'\r': command not found
bash: bashrc: line 106: syntax error near unexpected token `elif'
'ash: bashrc: line 106: ` elif [ "$processor" = "x86_64" ]; then

KSK@PC-9862 ~/openfoam/openfoam-1.4/.openfoam-1.4


What can cause this line of errors?

I have installed cygwin previous to this with out problems.

Best Regards
Kasper

Sometimes the errors are simply like this:

KSK@PC-9862 ~/openfoam/openfoam-1.4/.openfoam-1.4
$ . bashrc
bash: $'\r': command not found
bash: $'\r': command not found
bash: bashrc: line 106: syntax error near unexpected token `elif'
