HI Foamers!


I am learning snappyHexMesh, trying to create mesh. But I am receiving error as:
Setting up information for layer truncation ...
--------------------------------------------------------------------------
mpirun noticed that process rank 0 with PID 0 on node bidesh exited on signal 9 (Killed).


My snappyHexMeshDict:
#includeEtc "caseDicts/mesh/generation/snappyHexMeshDict.cfg"


castellatedMesh on;
snap on;
addLayers on;


geometry
{
RotorGGI
{
type triSurfaceMesh;
file "RotorGGI.stl";
//~ scale 0.001;
}
};


castellatedMeshControls
{

maxLocalCells 1000000;


maxGlobalCells 20000000;


minRefinementCells 100;


features
(
{ file "RotorGGI.eMesh"; level 3; }//2;
);


refinementSurfaces
{
RotorGGI
{
level (3 4);
}
}

resolveFeatureAngle 30;


refinementRegions
{


}
locationInMesh (0.0 0.0 0.0);
//~ locationInMesh (0.040858 0.635 -0.005742); // Offset from (0 0 0) to avoid
//~ locationInMesh (-0.040858 -0.635 -0.005742); // Offset from (0 0 0) to avoid
// coinciding with face or edge
nCellsBetweenLevels 5;//3;
}


snapControls
{
// explicitFeatureSnap true;
// implicitFeatureSnap false;
}


addLayersControls
{
layers
{
"RotorGGI.*"
{
nSurfaceLayers 7;//5;
}
//~ bottom
//~ {
//~ nSurfaceLayers 6;
//~ }
}


expansionRatio 1.1;


finalLayerThickness 3e-4;


minThickness 1e-7;


nGrow 0;


featureAngle 60;


slipFeatureAngle 30;


nRelaxIter 3;


nSmoothSurfaceNormals 1;


nSmoothNormals 3;


nSmoothThickness 10;


maxFaceThicknessRatio 0.5;


maxThicknessToMedialRatio 0.3;


minMedialAxisAngle 90;


nBufferCellsNoExtrude 0;


nLayerIter 50;

relativeSizes true;


// maxThicknessToMedialRatio 0.6;
}


meshQualityControls
{
minTetQuality -1e+30;
relaxed
{
maxNonOrtho 75;
}
}


/*writeFlags
(
// scalarLevels
layerSets
layerFields
); */


mergeTolerance 1e-6;
debug 0;


I was running with 3 processors.


One More problem. I have foam extend 4 and OF18 in my computer. When I run the command for snappy, I use OF18 version. I am receiving some strange things in terminal:


--> FOAM Warning :
From function void* Foam::dlOpen(const Foam::fileName&, bool)
in file POSIX.C at line 1601
dlopen error : liblduSolvers.so: cannot open shared object file: No such file or directory




Can anyone kindly help me to understand these issues.
Thank you.
