Hi,
I am trying to make a Foam model ,using simpleFoam, but Foam complains with an error that I don't understand. I would like to correct myself but the error message is too complicated for me...
Here is the error (I am running in parallel with 14 threads, on a machine named "titan"):
Code:
[12] #0  Foam::error::printStack(Foam::Ostream&)[4] #0[1] #0  Foam::error::printStack(Foam::Ostream&)  Foam::error::printStack(Foam::Ostream&)[0] #0  Foam::error::printStack(Foam::Ostream&)[8] #0  Foam::error::printStack(Foam::Ostream&) in "/opt/OpenFOAM/OpenFOAM-2.1.x/platforms/linux64GccDPOpt/lib/libOpenFOAM.so"

(sorry for this ugly presentation, but at least it is complete!)

Here is the log file:

I tried to initialize k uniform .72 and epsilon uniform .002 (to avoid bas 0 values).

I really don't understand what's happening...

I am using swak4foam for boundary conditions in my inlet. U, k and epsilon are type groovyBC, with expression as fallow:
U >> "vector(2.09*log(pos().z/2+5),0,0)";
k >> "1.05-.0033*pos().z";
epsilon >> "(.66-.002*pos().z)/((pos().z/2+5)*log(pos().z/2+5))";

Corresponding are:
p >> type zeroGradient;
nut >> type calculated

I don't understand what's wrong... I don't know if I gave you enough details to help me; but I can give you other dictionaries, parameters...

Thanks in advance.

Hi,
It seems that the problem comes from groovyBC:
1/ the case does not work neither in serial mode
2/ replacing the groovyBC by a fixedValue BC, it works!
More precisely, here are the two answer of simpleFoam:
With fixedValue (working):
PHP Code:
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

With groovyBC (not working):
PHP Code:

(...) 
I tried both with
libs ( "libgroovyBC.so" ) ;
and
libs ( "libOpenFOAM.so" "libgroovyBC.so" ) ;
in my controldict, but with same lack of success.

I should precise:
swakVersion: 0.2.1 (Release date: 2012-10-18)


It tried both with pts().z and pos().z, but again with same lack of success.

So I think something's wrong with groovyBC. Any help would be very useful, thanks!

Default error not groovyBC, but in the expression

Hi! I found one mistake: my calculated k value was incorrect (negative for high z values).
I changed :
k >> "pos().z>250 ? .225 : 1.05-.0033*pos().z";
epsilon >> "pos().z<250 ? (.66-.002*pos().z)/((pos().z/2+5)*log(pos().z/2+5)) : .141/((pos().z/2+5)*log(pos().z/2+5))";

But it still does not work. By the way, with:
k >> "pos().z>250 ? .225 : 1.05-.0033*pos().z";
epsilon >> type fixedValue
value uniform 0.002)
it works!

So finally, I think there is no problem with groovyBC (my excuses for the author), but with the expression. Does anybody knows why it does not work?

Thanks in advance
