<p class="MsoNormal">I took a look at your data, and the warp by vector filter is behaving exactly how I would expect.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The displacement field in your data is 0 everywhere except at the top edge. Thus, when you apply the warp the top edge will move and everything else will stay fixed where it is. In the middle of the top edge the warp vectors are pushing
down into the rest of the mesh. This is causing some self-intersection with the mesh, which is why you are seeing the pressure profile sticking out the top.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">You can use the Threshold filter to remove all cells that are not moving. However, that is only going to leave the top layer of cells, which I’m not sure what you want.<o:p></o:p></p>

<p class="MsoNormal">Dear all,<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">On a 2d model, I am trying to plot some mode shape for a coupled fluid-structure problem where a beam is coupled to a cavity domain. I have two variables for this problem: scalar pressure variable for the cavity and the displacement vectors
for the beam at the top edges of the domain. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I am writing the attached vtk input file with my post processing codes.
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">And the result is somewhat as expected except that another pressure profile with an undeformed structural part is also visible with what I actually want to get. Please see the attached screenshot with the settings and visible fields.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Do I have a misunderstanding to accomplish this task. At the end, I would like to show the pressure profile which is a scalar field in the file along with the displacement field on the beam at the top edge.
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I was thinking if there is deformed+undeformed visibility selection somehwere or not, maybe the issue is completely something else.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>

<p class="MsoNormal">Any comments are appreciated.<o:p></o:p></p>

<p class="MsoNormal">P.S. For a decent view for the deformed vector field, you can set the scale factor of the warpbyvector field to 0.1 to 0.15<o:p></o:p></p>
