Hi,

New question concerning proper installation of a groovyBC. I have some strange situation here and maybe some of you know what it is.

So, when I'm trying to run the simulation, using groovyBC, then I get something like below:

#0  Foam::error::printStack(Foam::Ostream&) in "/home/piotr/OpenFOAM/OpenFOAM-1.6.x/lib/linux64GccDPOpt/libOpenFOAM.so"
#1  Foam::sigFpe::sigFpeHandler(int) in "/home/piotr/OpenFOAM/OpenFOAM-1.6.x/lib/linux64GccDPOpt/libOpenFOAM.so"
#2  ?? in "/lib/libc.so.6"
#3  Foam::divide(Foam::Field<double>&, double const&, Foam::UList<double> const&) in "/home/piotr/OpenFOAM/OpenFOAM-1.6.x/lib/linux64GccDPOpt/libOpenFOAM.so"
#4  Foam::tmp<Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh> > Foam::operator/<Foam::fvPatchField, Foam::volMesh>(Foam::dimensioned<double> const&, Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh> const&) in "/home/piotr/OpenFOAM/OpenFOAM-1.6.x/applications/bin/linux64GccDPOpt/compressibleInterFoam"
#5  main in "/home/piotr/OpenFOAM/OpenFOAM-1.6.x/applications/bin/linux64GccDPOpt/compressibleInterFoam"
#6  __libc_start_main in "/lib/libc.so.6"
#7  _start at /build/buildd/eglibc-2.10.1/csu/../sysdeps/x86_64/elf/start.S:116
Floating point exception

Of course I've put a line in a controlDict:

libs ( "libOpenFOAM.so" "libgroovyBC.so" ) ;

but it doesn't work.

I feel that probably I made something wrong during the "installation" of groovyBC on my machine. Is it all right, that the path to the groovy library is:

./OpenFOAM/piotr-1.6.x/lib/linux64GccDPOpt/libgroovyBC.so

instead of:

./OpenFOAM/OpenFOAM-1.6.x/lib/linux64GccDPOpt/

Is it ok?

I think it is OK. Generally, we should put library in our own directory. Did you run the demo case in groovyBC package?

Good point, I have to check it...

---------
OK I checked that. I ran the average-t-junction case and it crashed after the step t=0.429104 and just before calculating deltaT of the next step:

Courant Number mean: 2.06335e+30 max: 6.04513e+31
#0  Foam::error::printStack(Foam::Ostream&) in "/home/piotr/OpenFOAM/OpenFOAM-1.6.x/lib/linux64GccDPOpt/libOpenFOAM.so"
#1  Foam::sigFpe::sigFpeHandler(int) in "/home/piotr/OpenFOAM/OpenFOAM-1.6.x/lib/linux64GccDPOpt/libOpenFOAM.so"
#2  ?? in "/lib/libc.so.6"
#3  Foam::Time::adjustDeltaT() in "/home/piotr/OpenFOAM/OpenFOAM-1.6.x/lib/linux64GccDPOpt/libOpenFOAM.so"
#4  main in "/home/piotr/OpenFOAM/OpenFOAM-1.6.x/applications/bin/linux64GccDPOpt/pimpleFoam"
#5  __libc_start_main in "/lib/libc.so.6"
#6  _start at /build/buildd/eglibc-2.10.1/csu/../sysdeps/x86_64/elf/start.S:116
Floating point exception

So there is a problem for sure, but this time different (only first 3 lines are exactly the same) than before, even though stinks the same...
--------
This time I ran wobbler. The simulation went smoothly without any errors and the results looks quite nice in ParaView. Strange

There is no place in the stack-trace that says "groovyBC" so the problem didn't happen during the execution of groovyBC. Nevertheless it is possible that you used groovyBC to set something to 0 that shouldn't be 0 (the stack-trace indicates division by 0). But that is something groovyBC cannot be held responsible for

Bernhard is right, this error is simply due to my lack of knowledge. Sorry Bernhard... and thanks for all hints.
