[Paraview] Resampling an Unstructured Grid

It was not clear in your email, but I am assuming that the points marked invalid are actually inside a cell in the unstructured mesh and should not have been marked so.  You also stated that they happen near where the resolution of the unstructured grid changes.  That can mean multiple things, but I am assuming that you are referring to a discontinuity in the grid where coarse cells share a face with multiple finer cells.  If this is the case, then VTK is going to have problems because many of its algorithms, including finding the cell in which a point belongs, relies on being able to find a cell's neighbors, and this is ill defined when you have a discontinuity.

Dear all,

I am using the ResampleWithDataset filter to interpolate values from an
unstructured grid to a grid of equally spaced points.
