[Paraview-developers] D3 and higher order elements

[Moreland, Kenneth]

Ideally, D3 (or its replacement) and the ghost cell generator would work correctly for higher order elements. I can’t think of anything special about non-linear elements that would make it particularly harder to partition or find ghost cells. As long as you are not clipping the cells, there is no interpolation that needs to be done.

Subject: [EXTERNAL] [Paraview-developers] D3 and higher order elements

I have a user that tried to run the D3 filter on higher order elements.  D3 failed, silently.  The confusing hack was to run the Tesselate filter before D3.  What is the correct solution?

·         Have D3 deal with higher order elements?  Ditto the Ghost Cell Generator?

·         Have D3 and Ghost Cell Generator call Tesselate filter under the covers?

·         Have an output warning message that D3 is failing due to higher order elements?

I would argue for the first or second.  Thoughts?
