Hello everybody!
If you like fancy legends in your graphics, text with the full power of latex, then you have to give a try to Hrv's dxFoam reader together with some extra macros from dxfontutils. If you don't manage to install the dxfontutils, check this post: install dxfontutils

I hope you will like it!

Hello!

I finished building OpenFOAM on our 64 bit altix system and I would like to visualize the results of the icoFoam example described in the README file. ParaView doesn't work, so I'd like to try OpenDX. Is there a way to enable the dx output features in OpenFOAM or do I need to use dxFoamExec?

Thanks!

George

hjasak will become famous soon enough
1.4.1-dev comes with a dx reader module:

See: http://openfoam-extend.svn.sourcefor...trunk/Core/Ope nFOAM-1.4.1-dev/applications/utilities/postProcessing/graphics/dxFoamExec/

Enjoy,

Hrv

You have to use dxFoam if you want to see the results in OpenDX. In other words, there is no "foamToDX" written yet.

Thanks!

Two problems remain:

1) Where would I find dxFoam?

2) I assume I must put dxFoamExec in OpenFOAM-1.4.1/applications/utilities/postProcessing/graphics/
and then try and build it from there. Is this correct?

Thanks,
George

Hi Dragos,

I know that dxFoam is included in OpenFOAM-1.4.1-dev, in fact, i have both OF 1.4.1, and OF 1.4.1-dev in my laptop, since, despite the fact that i can isnstall and run all the utilities of OF 1.4.1 including FoamX, the same does not apply to OF 1.4.1-dev : when i type FoamX& under a bash shell sourced with
.$HOME/OpenFOAM/OpenFOAM-1.4.1-dev/.OpenFOAM-1.4.1-dev/bashrc,
i get

Cannot find JDK at /usr/lib/jvm/java-1.5.0-sun. Please set JAVA_PATH to the
JDK installation directory.

And i have followed the same process of installation that i used with OF 1.4.1 :

/root/OpenFOAM will hold both ./OpenFOAM-1.4.1-dev and ./linux ;

./linux will hold ./dx-4.4.4, ./gcc-4.2.1, ./j2sdk1.4.2_05 and ./paraview-2.4.4.

Here is my foamInstallationTest

The foam installation contains 1 critical error(s).

Review the output for warning messages and consult
the installation guide for trouble shooting.

I do not know why isn't JAVA_PATH correctly set, nor how can i solve it editing some of OF configuration files, i installed it the same way i did with OF-1.4.1, and -1.4.1 works fine...

My other problem is that i cannot put dxFoam to work, bash complaints that it cannot find dxFoamExec executable; so i

find /root/OpenFOAM/OpenFOAM-1.4.1-dev -name dxFoamExec

the results are :

/root/OpenFOAM/OpenFOAM-1.4.1-dev/applications/utilities/postProcessing/graphics /dxFoamExec

as expected, so
cd /root/OpenFOAM/OpenFOAM-1.4.1-dev/applications/utilities/postProcessing/graphics /dxFoamExec

wmake

It gives out all that gibberish of making and compiling and exits with an error, three last lines are:

/usr/bin/ld: cannot find -lssp
collect2: ld returned 1 exit status
make: *** [/root/OpenFOAM/OpenFOAM-1.4.1-dev/applications/bin/linuxGccDPOpt/dxFoamExec] Error 1

I do not know what else to do to get OpenDx working with OpenFOAM... since there are problems with ParaView with huge datasets, one of them is the streamlines issue, they get broken...

BTW, I use Ubuntu 7.10, and added dx from the repositories, is there any way I could use the version that I have installed in Ubuntu, since i do not know how to use/configure the one that i have installed in /root/OpenFOAM/linux...?

Is there any tweak that i can use to :

1) get FoamX to work under OF 1.4.1-dev ?
2) wmake dxFoamExec so that i can use it in PostProcessing ?

3) if none of this works, get dx from Ubuntu repositories to work with OF...?

Thanks in advance

Alex

Hi Alexandre,
First it seems there is a problem with your java installation path:
$JAVA_PATH /usr/lib/jvm/java-1.5.0-sun no no
then there is also an error with your gcc path:
gcc 4.1.3
WARNING: Conflicting installations:
foam settings: /root/OpenFOAM/linux/gcc-4.2.2/bin/gcc
current path : /usr/bin/gcc
CRITICAL ERROR

So first fix these two, and then you can worry about dx.
Check if you have java in the requested path (if no make it so). The same goes for gcc.
I don't know if ubuntu comes with the libraries for dx. If it does you will have to tell that to OpenFOAM environment variables (check the value of $DXROOT). Otherwise you will have to download, compile and use dx-4.4.4.

Hi Alex,
The problem with gcc is that your version is not the right one: OpenFOAM-1.4.1-dev wants gcc-4.2.2 and you have gcc-4.2.1 in your linux directory (which is ok for OpenFOAM-1.4.1).

Thx Dragos,

I Partially solved the prob...

PARTIALLY... I changed gcc to gcc-4.2.2, in fact, i untared all the *.bin.tgz contents of ./linux folder i have downloaded from http://powerlab.fsb.hr/ped/kturbo/OpenFOAM/release/ in my ~/OpenFOAM/linux.

Used the ~/.bashrc source for OpenFOAM-1.4.1-dev and started in that shell FoamX&, still no sign of it, but after making export JAVA_PATH=~/OpenFOAM/linux/jds.. whatever the error message changes from Cannot find JDK at /usr/lib/jvm/java-1.5.0-sun. Please set JAVA_PATH to the
JDK installation directory.

/root/OpenFOAM/linux/dx-4.4.4/dx/bin_linux/dxui: symbol lookup error: /root/OpenFOAM/linux/dx-4.4.4/dx/bin_linux/dxui: undefined symbol: _XmStrings2


Seems there is something quite wron with OF_1.4.1-dev installation, but i just cannot figure out what...

Even tried to compare the ~/OpenFOAM-1.4.1/.OpenFOAM-1.4.1/bashrc with the ~/OpenFOAM-1.4.1-dev/.OpenFOAM-1.4.1-dev/bashrc so see if there's any major difference, but i guess that the differences that i have noticed are not related to my problem... :-(

I think that OpenDx might be a more robust tool for post processing than paraview, so i'd really like to try OpenFOAM-1.4.1-dev ...

Hi Alex,
It seems that your OpenDX installation is not working. What happens if you run directly OpenDX, if you type dx? If it works then I'm clueless, but I would expect to get the same error.

Hi Dragos,

I have two Dx installs in Ubuntu.

One i have imported from repos, it runs out from bash shell wether i have OF environment sourced or not, when i type dx at the prompt. It was correctly installed with synaptic, i have already run the tutorials, it accepts a fluent data explorer data export... so, seems it is working ok.

I have also installed the dx....bin.tgz from http://powerlab.fsb.hr... in my ~/OpenFOAM/linux folder, so that OF would find it, when it is called from within OF.

The same happens with Paraview, i have 2.4.4 *.bin.tgz installed in ~/OpenFOAM/linux and i use it... either from OpenFOAM-1.4.1 or OpenFOAM-1.4.1-dev...

And i also have Paraview 3.... (whatever) installed in my /usr/local/paraview, since it is much more robust to huge datasets in .ensignt export format (less core dumps...)

Meaning that... even having two Paraview installs, OpenFOAM correctly selects 2.4.4 as its default viewer... it is installed in OF/linux.. well, same thing should apply to Dx... I guess i am being logical here...

Why doe it complains about _XmStrings2 undefined symbol in /root/OpenFOAM/linux/dx-4.4.4/dx/bin_linux/dxui...?


when OF-1.4.1-dev environment is sourced from a shell, JAVA_PATH should be pointing to /root/OpenFOAM/linux/j... but it doesnt... even when i export it, there is an error, it finds java, but there's an error in Java...

...dunno what else to do... :-(

Guess i will have to stick to OF-1.4.1 and Paraview 2.4.4. broken streamlines... :-(

Did you try to run this from the command line? I ask because you mention only the Ubuntu installation of OpenDX working and not this one (whereas this is the one that OpenFOAM tries to use).

So i guess that the only thing missing is the dynamic linker...lib/ld-linux.so.2

meaning that this version of OpendDX has been dynamically linked against a previous version of GLIBC, am i right...?

... Guess what...

I have downloaded dx-4.4.4.tar.gz to my desktop, extracted, and tried to compile it myself.

cd /home/alex/Desktop/dx-4.4.4
./configure

...ended up with

checking lex output file root... configure: error: cannot find output from :; giving up

I dont know if i can build it in Ubuntu without mangling my OS...

in the README file it states that it needs Motif, Open Source implementations have unpredictable behavior...

Hi Alex,
Indeed compiling OpenDX is not that straight forward, sometimes. But if you have a running installation on your system why don't you use that?
Just change the environment variable DXROOT in ~/OpenFOAM/OpenFOAM-1.4.1-dev/.OpenFOAM-1.4.1-dev/apps/dxFoam/bashrc:
export DXROOT=$WM_PROJECT_INST_DIR/$WM_ARCH/dx-4.4.4/dx
from the current value to something appropriate to you!

Hi Dragos,

Success... :-)

Changed ~/OpenFOAM/OpenFOAM-1.4.1-dev/.OpenFOAM-1.4.1-dev/apps/dxFoam/bashrc

and made DXROOT point to /usr/lib/dx

dxFoam works... i think... :-)

So where should i place my .net file so that dxFoam correctly reads my case...?

What is the correct syntax od dxFoam...?

is it just dxFoam plain or dxFoam . <case> [options]....?

From the beginning of this topic i see that there is a folder ~/OpenFOAM/OpenFOAM-1.3/.OpenFOAM-1.3/apps/dxFoam/network

that in my case should be
~/OpenFOAM/OpenFOAM-1.4.1-dev/.OpenFOAM-1.4.1-dev/apps/dxFoam/network


Inside this folder i find
drwxr-xr-x 2 alex alex 4096 2008-04-10 00:07 macros
-rw-r----- 1 alex alex 90413 2007-11-22 08:43 postFoam.cfg
-rw-r----- 1 alex alex 495410 2007-11-22 08:43 postFoam.net
-rw-r--r-- 1 root root 30633 2008-04-10 02:10 simple.net

When i type dxFoam simple it doesn not allow me to select any case, shoul i invoke it from within a case directory?

What is the difference from simple.net and postFoam.net ?

When i try dxFoam postFoam, i get several CFD related menus that i do not get from dxFoam simple, but also a lot of warnings against unrecognized comments, and one final error about an undefined tool... and also that i should reload the visual program after loading the tool ExcludeList...

Any Hints...?
