Re: [Paraview] How to test for empty block in multi-block dataset

2017-10-18 Thread Andy Bauer 
Hi Dennis,

I think something like:
if multiblock.GetBlock(i) != None:
  ...

should work. You probably don't even need the "!=None" part.

Cheers,
Andy

P.S.  I'm writing python inside a Programmable Filter

Thanks again

[Paraview] How to test for empty block in multi-block dataset

2017-10-18 Thread Dennis Conklin 
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
