Hi Kazuyoshi,
I do not think the glyph filter will do what you want it to. You might use a
Python programmable filter[1] to turn each point into a line segment (i.e., a
line from (x,y,z) to (x+dx, y+dy, z+dz)). Then run "Cell Centers" on the
resulting line segment data and add oriented, unscale

Hi all,
The Exodus reader creates 8 top-level blocks to identify different types of
data present in each file (corresponding to the names you see for 0-7). Each of
these blocks contains child blocks for the actual data loaded from the file
