Dear Forum

Wish you all a very nice day.

I have come across a strange error while using
LaunderGibsonRSTM on SGI ALTIX 4700. I am using dev version and it has been compiled with Intel 10.0. Below provided is the MPI traceback.

I request the experts to take a look at it. I do not understand most of the cryptic stuff the traceback has thrown out.

The case (with LaunderGibsonRSTM ) does not runs even with a single processor.It gives out a floating point exception error. Changing the turbulence model to kEpsilon or RNGkEpsilon leads to a successful run.

The same case work normally on a GNU compiled development version without any error.

Dear Forum

Good Evening.

Digging in for the source of error this is what I found:


LaunderGibsonRSTM has alongwith other objects:

(in LaunderGibsonRSTM.H file) wallDistReflection yr_;
(in LaunderGibsonRSTM.C file) yr_(mesh_) is initialized.

Next looking into wallDistReflection.H and .C, its
constructor is defined as:
-----------
Foam::wallDistReflection::wallDistReflection
(
const Foam::fvMesh& mesh,
const bool correctWalls
)
:
reflectionVectors(mesh),
wallDistData<wallpointdata<vector> >
(
mesh,
reflectionVectors::n_,
correctWalls
)
{}
------
reflectionVectors(mesh) shows no errors.

The source of error lies in wallDistData. Its constructor is defined as :
----------------------
template<class>
Foam::wallDistData<transfertype>::wallDistData
(
const Foam::fvMesh& mesh,
GeometricField<type,>& field,
const bool correctWalls
)
:
volScalarField
(
IOobject
(
"y",
mesh.time().timeName(),
mesh
),
mesh,
dimensionedScalar("y", dimLength, GREAT)
),
cellDistFuncs(mesh),
field_(field),
correctWalls_(correctWalls),
nUnset_(0)
{
correct();
}
----------------------
Everything is initialized but when the function correct() is called the simulation crashses with floating point exception error.

This is what the case run shows (with debug switches on) just before it crashes:

Let's keep in touch, for I use IRIX too, and I am suffering the same error as you.
