Contrib/swak4Foam
 

Hi,

sorry for that very low skilled question, but I don't succeed on myself...

How to install and work with the library swak4Foam ?

Hot link: http://openfoamwiki.net/index.php/Contrib/swak4Foam

I just don't what to do. I tried on my own but nothing really good...

Can anybody "give me his hand" with a step-by-step help ?

Could you please be more specific where you're having the problems? Download it as described in http://openfoamwiki.net/index.php/Co...am#Downloading Then go to the README-file as indicated there (Basically all you've got to do is say ./Allwmake in the right directory)

After executing
svn checkout https://openfoam-extend.svn.sourceforge.net/svnroot/openfoam-extend/trunk/Breeder_2.0/libraries/swak4Foam/ ,
I typed ./Allwmake

The first lines were:

The last lines were:

Let's accentuate the positive ;) : the stuff in Libraries compiled and linked OK?

Yours is a fairly recent Linux, right? There has been a change in the linker where dynamic links are not implicitly linked anymore and my suspicion is that this is the case here.

Try the following: in Utilities/replayTransientBC/Make/options change the line

-lmeshTools

to

-lmeshTools -ltriSurface

and see if anything changes

not better
 

Nothing better:

and at the end:
When I run my case, it does not work:
Some help?

In fact that IS better because there is a new error (which means we're on the right track). Try adding "-lPStream" to that line.

Anyway: what kind of Linux are you using (my prejudices say "Ubuntu") and could you check which versions are the dynamic linker and the compiler ("ld -V" and "gcc -v" give you that information)

For the groovyBC-problem: there must be something about a dynamic-lib not loading further up in the output

Bernhard , thanks a lot. I don't know what I'd do without your kind help.

About my installation:

Linux version:
SUSE LINUX
Release 11.4 (Celadon)
Kernel Linux 2.6.37.1-1.2-desktop
GNOME 2.32.1

About ./allMake :

Beginning:
Ending:
Just to ckeck: you meant "lPStream", with an l like lambda (lowercase) then P like principle (uppercase) ?

OK. That's not as bleeding edge as I suspected

But the libraries are alright? (you should see lines like "'..../libgroovyBC.so' is up to date")
Exactly. Except that I mistyped and the "S" should be lowercase ( -lPstream)

At the beginning, I can read:

But the end:

But it still doesn't work:

The library should be in $FOAM_MPI_LIBBIN. Check with
ls $FOAM_MPI_LIBBIN
whether this is set on your system. If yes: add
-L$(FOAM_MPI_LIBBIN)
at the start(!) of the line you've already been editing in Make/options

This is not my fault. The binary distro you're using (I assume from the path that you didn't compile OF yourself) seems to be broken for compilations


I guess you added groovyBC to the libs-list in the controlDict, right? In that case check further up in the solver output: there should be some error about not being able to load it. If not recheck the libs-entry

Hi Bernhard!
OK. I understood that you think my installation is not as "clean" as possible.
So I will try to reinstall everything.
Right now, I am updating my system (zipper, yast,...), and then, I will fallow the instructions of http://www.openfoam.org/download/suse.php
Does it sounds good for you? Do you think I am in the correct path?

Re-install
 

I just installed OpenFOAM-2.1.0 from http://sourceforge.net/projects/foam/files/foam/suse/11.4/x86_64/
('cause my suse version is only 11.4).
I fallowed the instruction of official OpenFOAM page http://www.openfoam.org/download/suse.php
(rpm-i ... user configuration ... check on icofoam)
.

Then, I ran svn on swak4Foam .

And then ./Allwmake. Still the same problem. I added
-lmeshTools -ltriSurface -lPstream but it still dosn't work:
What should I do to use your nice suiss knife? It seems necessary for my case...

I THINK the problem is that the binary version of OF you're using is somehow a bit misconfigured for compilation (basically the flags miss a -L-option). Reinstalling won't fix that i'm afraid. Have you ever tried compiling other OF-software and did that work?

Greetings to all!

@Julien: I've just now finished testing on openSUSE 11.4 x86_64 with the RPM packages of OpenFOAM 2.1.0 and had no problems at all!
My guess is that the problem you're having is due to placing swak4Foam's code in the folder "/opt/OpenFOAM-2.1.0/Telechargements/swak4Foam" :confused:.

After the OpenFOAM environment was ready to be used, I did:
The "WM_NCOMPPROCS" is for using 4 cores for faster building. Ran a second time the Allwmake command just to know if all was built successfully and it was all OK! I didn't need to change anything in swak4Foam's code!

Best regards,
Bruno

(Thanks everybody! I really appreciate your kind help !)

OK, I apologize. I wanted to make it nice, so I made a special folder for the downloads, in order not to "mix" everything, but know I know I was totally wrong...
Nevertheless, I did not understand from which cwd I should launch svn ?

As long as you don't want to compile your own software that is based on swak or if you don't want to use the swakCoded-functionObject this doesn't matter

Know, swak4foam is in /home/me/OpenFOAM/me-2.1.0/run
So, I made
cd swak4Foam/
./Alwmake
There is still the errors.

It works now !
 

Bernhard, Bruno , :) thanks a lot :) . I think I found.

Compiling problems:
I had to change several /Make/option files:

• for funkyDoCalc , funkySetBoundaryField and funkySetFields, I added the libraries -ltriSurface -lsampling -llagrangian -lPstream -lfileFormats -lsurfMesh -lconversion
• for replayTransientBC , only -ltriSurface and -lPstream

BUT I had ALSO to move
/opt/OpenFOAM-2.1.0/platforms/linux64GccDPOpt/lib/dummy/libPstrem.so
to
/opt/OpenFOAM-2.1.0/platforms/linux64GccDPOpt/lib/
(??? Why was it in a "dummy" folder ???)

Now it's working! 'hope my post could help somebody else...

Bernhard: updateded my controlDict . I works now.

Once again, thanks a lot !

PS: do you think I should post a nethreaded, clean, in order to share my solution without all the rough exchanges with no interest?

Got to catch this quickly before Bruno does. He's only 19 posts behind me and at the rate he's posting my estimate is that he'll overtake me before the weekend

The dummy-folder holds a non-parallelized version of Pstream that is only needed to bootstrap the compilation process of OpenFOAM. Usually there should be another folder named after you mpi-implementation (openmpi-1.5 or so) with the correct Pstream (the variable $FOAM_MPI_LIBBIN points to it).
Not sure whether your stuff will no work in parallel
Would be nice to have a bug-report on the mantis with the changes required to Make/options so that it will get into the next release. The Pstream-moving .... I still think that this is a problem of the binaries you installed

Hi Bernhard and Julien,

@Bernhard:
What can I say, I'm helping people on the forum instead of playing WoW ;)
(And I got my powers upgraded a week and a half ago :rolleyes: nothing like whirling an axe at a spammer :D)



@Julien: OK, having to hack around in OpenFOAM's installation folder, usually can only mean one thing: you've got a contaminated shell environment. Let me explain: your "$HOME/.bashrc" probably has something like this:
When you should have something this:
The alias commands create command shortcuts, namely the newly created aliases of201 and of210.
Now, whenever you start a new terminal window/tab, you should run only one of the aliases above:

• In a new terminal where you need OpenFOAM 2.0.1, run:
  Code:

  ---

  of201

  ---

• In a new terminal where you need OpenFOAM 2.1.0, run:
  Code:

  ---

  of210

  ---

• If you need to switch between versions inside the same terminal, here's what you do to switch from 2.1.0 to 2.0.1:
  Code:

  ---

  wmUNSET
of210

  ---

The other possibility is that you might have skipped some important step... for example, might not have installed Open-MPI - what does this command output:
