Hi there,

I've recently installed swak4Foam with OpenFOAM 1.7.1.
It seems to have compiled successfully. However when I run one of the tutorials with in swak4Foam (in this case the pulsedPitzDaily case in groovyBC) I get the following feedback.

Floating point exception

I found this a bit strange, I also have two other bits of code I'm using for a project. These were working before I installed swak4FOAM but now they get a similar error message.

Can someone tell me what's going on, or help with a solution?

Best Regards,

Greetings Steven and welcome to the forum!

OK, you didn't mention the Gcc version, although you blamed it

A few questions:

• What Gcc version are you using?
• What Linux distribution and version are you using?
• Which swak4Foam version are you using?

There's a compatibility matrix showing the relation between OpenFOAM and Gcc versions: http://openfoamwiki.net/index.php/In...ibility_Matrix

Best regards,
Bruno

Hi Bruno,

Many thanks for your quick response! In answer to your questions:

gcc version 4.4.5 - according to the matrix it seems to be compatable with OF1.7.1.

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=10.10
DISTRIB_CODENAME=maverick
DISTRIB_DESCRIPTION="Ubuntu 10.10

I don't know what version of swak4Foam I've downloaded, but I downloaded it from this website: http://openfoamwiki.net/index.php/Contrib/swak4Foam

I used the command from the following section:
The current version that works with 1.x-releases of OpenFOAM can be downloaded using the following command..


Thank you for your time,


Steven

Hi Steven,

OK, first thing, we need bash as the default sh (the default in Ubuntu is dash):

sudo update-alternatives --install /bin/sh sh /bin/dash 1
sudo update-alternatives --install /bin/sh sh /bin/bash 1
sudo update-alternatives --config sh

Then pick "0".

Then install bison:

sudo apt-get install bison

If you want python integration as well, see the file "swakConfiguration.example" and copy-edit to "swakConfiguration".

Then build swak4Foam:

./Allwmake

If you still have problems, run it again like this:

./Allwmake > make.log 2>&1
tar -czf make.log.tar.gz make.log

Then attach "make.log.tar.gz" to your next post.

Best regards,
Bruno

The actual error you posted happens in a library that comes with OF so my lawyer told me do deny all responsibility

Anyway: the only way I can see swak being involved here is that the groovyBC wrote for instance a NaN and that lead to the floating point exception in another library (which is what you're seeing)

Starting with the latest release the utilities that come with swak4Foam (for instance funkySetFields) give a swak-version-number. If you're not seeing that then you don't have the latest release.

Greetings to all!

After Bernhard's post, I remembered that I forgot to check if the tutorial worked for me. I tested the tutorial "Examples/groovyBC/pulsedPitzDaily" by running:

blockMesh
pisoFoam

And It ran with no problems till 0.00037s, which was when I canceled execution, since the initial report indicated that it would crash at the first time step.

Best regards,
Bruno

Hi Everyone!

Many thanks for your advice and suggestions. I've got swak4Foam working now!

If any of the suggestions here was the right one OR if the problem was something different, could you just write one sentence about that here? Not for me but the next poor soul who has the same problem as you and finds this thread via the search-function of the MessageBoard

[S.J.Daniels]

Hello all,

Swak4Foam worked after I followed Bruno's instructions earlier in this thread (installing Bison etc.). I haven't tried the Python integration yet.

Thanks again,

Steven

Thanks for the clarification.

Python integration has potential. But don't spend too much time on it if you don't need it
