Clipping of fields on a P2 (quadratic) mesh does not show subdomain halos.
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
I have attached a .tar.bz2 file, which contains the necessary .pvtu and .vtu files to reproduce this bug.
Simply load the data and perform the clipping operation. You will see a void,which corresponds to the subdomain halos. Other filters, for example, the slice, do not show this issue.
I have reproduced this issue with both paraview and mayavi2, which seems to imply that it is a VTK problem.
Note that when I output on the P1 (i.e. linear) finite element mesh, this issue is not observed. It seems limited to output on the P2 (quadratic) mesh.
