vtkCutter no data at the boundary edge with current interpolation algorithm

Hello
I have a CFD postprocessing task with *.plt file as surface data source. After the surface data was imported via vtkTecplotReader, I tried to cut a slice at the symmetry boundary plane (Y=0 ) with “vtkCutter”. However, the slice turned to be empty with no point or cell data. Should I try another interpolation algorithm to get correct slice data at that boundary plane?

This is my code:
:

vtkNew<vtkPlane> plane;
plane->setOrigin(0,0,0);
plane->setNormal(0,1,0);
vtkNew<vtkTecplotReader> reader;
reader->setFileName(“xxx.plt”);
reader->Updata();
vtkNew<vtkCutter> cutter;
cutter->setCutFunction(plane);
cutter->Updata();

Thanks !
Best Regards
