Xdmf Reader mixup on GeometryType='ORIGIN_DXDYDZ'

This issue was created automatically from an original Mantis Issue. Further discussion may take place here.

The XDMF reader appears to have a bug with grids with a GeometryType of "ORIGIN_DXDYDZ". The documentation at http://www.xdmf.org/index.php/XDMF_Model_and_Format states:

ORIGIN_DXDYDZ - Six Values : Ox,Oy,Oz + Dx,Dy,Dz

This would imply that the Origin DataItem's three values would be, in order: "X, Y, Z". VisIt interprets these coordinates in this order as well. ParaView, on the other hand, interprets the coordinates as "Z, Y, X".

This becomes most noticeable when you have a larger grid made up of sub-grids, each with a GeometryType of ORIGIN_DXDYDZ, and they line up along the wrong axis.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
