Slice Sampling (interpolation)on ANSAgenerated mesh fails (glibc free),ok on SHM mesh
 

Hello,
I am using OF2.2 and I am having trouble running a sampling slice when working with a volume mesh generated with ANSA.

Here is my functionIncludeDict:

slices
{
type surfaces;
storeFilter false;
functionObjectLibs ( "libsampling.so" );
outputControl timeStep;
outputInterval 100;
setFormat raw;
surfaceFormat vtk;
interpolationScheme cellPoint;
fields U;
surfaces
(
X_Movie_0
{
type cuttingPlane;
planeType pointAndNormal;
pointAndNormalDict
{
normalVector (1.000000 0.000000 0.000000);
basePoint (-1.000000 -0.000000 -0.000000);
}
interpolate true;
mergeTol 1e-8;
}
);
}

When I run it (with execFlowFunctionObjects -latestTime ) I get the following error:
urfaces slices: Reading surface description:
X_Movie_0

======= Backtrace: =========
/lib64/libc.so.6(+0x750c6)[0x2b08c8f590c6]

Notice that:
1)The same dictionary works perfectly on a SnappyHexMesh generated mesh.
2)This dictionary works if I change the flag interpolate to false.

I have tried the other interpolation schemes options but those fail as well..

Any idea?

thanks,
matteo

p.s.: ANSA mesh is a mix tets,pyramids,hexa.
