All, I have a number of filters that process all the blocks in a multiblock dataset.
If I perform some preliminary processing, such as thresholding, I might end up with some empty blocks (contain no elements satisfying the Threshold, for instance) When I try to process an empty block, it kills Paraview. I tried testing for block.GetNumberOfCells()>0, but calling GetNumberOfCells() on an empty block seems to kill Paraview all on it's own. Is there a test I can do to detect an empty block without killing the program? Thanks Dennis
