<div>Hi afad sfgsfdgsfd,<br>
<br>
Fixes for bugs introduced by changes in VTK's xml file
format are in the pipeline, so you'll have to checkout the
latest git HEAD and build ParaView from source to get the
bug fixes. If that's something you're willing to do, here
are first steps<br>
<br>
# get sources<br>
$ git clone --recursive git://<a moz-do-not-send="true"
href="http://www.paraview.org/ParaView.git"
target="_blank">www.paraview.org/ParaView.git</a><br>
# apply the patch<br>
# patch is attached and I just now submitted to PV, will
show up in PV after the next review.<br>
$ cd ParaView<br>
$ git am -3
0001-QuadraturePoints-any-integer-type-for-offsets.patch<br>
# build pv<br>
<br>
That will get you the bug fixes. Build it, use default
build opts is fine. <br>
<br>
Then if you like you can get the test data, and open the
file ParaViewData/Data/blow.vtk, construct the pipeline
showed in the post (<a moz-do-not-send="true"
href="http://markmail.org/message/6qz3ebszvny4vwxp#query:+page:1+mid:6qz3ebszvny4vwxp+state:results"
target="_blank">http://markmail.org/message/6qz3ebszvny4vwxp#query:+page:1+mid:6qz3ebszvny4vwxp+state:results</a>).
That shows how it's supposed to work.<br>
<br>
$ git clone <a moz-do-not-send="true"
href="http://www.paraview.org/ParaViewData.git"
target="_blank">www.paraview.org/ParaViewData.git</a><br>
<br>
Now onto your data, the xml you gave is incorrect , it's
missing the offset array. let me see if I can get your
example working, I'll post a follow up, hopefully in a few
minutes.<br>

<div dir="ltr"> I am trying to understand quadrature in
paraview. I am running finite element simulations in
which I have displacements at the nodes of the element,
and stress/strain at the quadrature points. I have
linear and quadratic hexahedral or tetrahedral elements.
I have been spending days trying to figure out how to
implement data on the quadrature points. I have
downloaded just about every document I can find.
<div><br>
</div>
<div>First: I downloaded CylinderQuadratic.vtk as shown
in VTK-Quadrature-Point-Design-Doc. I was able to
generate the quadrature scheme dictioanary and
generate quadrature points. But, when I tried to use
the Interpolate to Quadrature Points filter I could
not select QuadratureOffset in the Select Source Array
drop down menu. I was able to do this when using the
Generate Quadrature Points filter. </div>
<div><br>
</div>
<div>Second: Considering I couldn't figure out how to
interpolate quadrature points using
CylinderQuadratic.vtk, I decided to investigate just
using a single element. I took quadraticTetra01.vtu
and modified it to only have on quadratic tetrahedron.
Then I used paraview to generate the quadrature
scheme dictionary. I saved this into a VTU file in
order to see how to implement the dictionary on my
own. When I tried to reopen this new VTU file,
paraview was unable to open the file. Specifically,
it choked on the QuadratureOffset data array.</div>
<div>This is the file that paraview cannot open</div>

<div>Third: I investigated quadrature for hexahedron.
I made a similar file to quadraticTetra01.vtu and
tried to generate a quadrature dictionary. Upon
hitting apply for this, paraview crashes. It crashes
for both linear and quadratic hexahedron. This is the
file it crashes on,</div>
