I'm working with an Xdmf dataset in ParaView 3.10.1 that has multiple unstructured-grid blocks with overlap regions, however doens't seem to actually have "ghost" cells. This means when I extract an isosurface, I wind up with perfectly overlapping faces.
I can use the Clean filter to eliminate coincident points, but but coincident faces. As an example, if I use the "Select Cells Through" option to select 2 triangles on an overlapping border, I get 4 points (normal for 2 triangles) but 5 cells, with perfect overlap. The results from an ASCII VTK File saved to disk:
vtk output ASCII DATASET POLYDATA POINTS 4 float 1.37916 0.965356 0.21928 1.37129 0.964077 0.218481 1.37613 0.958331 0.219823 1.36947 0.958944 0.21948 POLYGONS 5 20 3 0 1 2 3 2 1 3 3 0 1 2 3 2 1 3 3 2 1 3
Is there any filter in ParaView capable of fixing this? Or does it have to be an arduously slow Python script to run in a Programmable Filter?
