Re: [Paraview] warp by vector field(displacement) with pressure field problem

[Moreland, Kenneth via ParaView]

Umit,

I took a look at your data, and the warp by vector filter is behaving exactly 
how I would expect.

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.

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.

Subject: [EXTERNAL] [Paraview] warp by vector field(displacement) with pressure 
field problem

Dear all,

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.

I am writing the attached vtk input file with my post processing codes.

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.

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.

I was thinking if there is deformed+undeformed visibility selection somehwere 
or not, maybe the issue is completely something else.

Any comments are appreciated.

BR,
Umut

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

Re: [Paraview] No labels on Axes Grid to show object dimensions

[Cory Quammen]

Umut,

Great, glad to hear it.

Which of the settings, "Depth Peeling" or "Depth Peeling for Volumes",
caused the problem? Or was it both?

I'll fill an issue on our bug tracker, but I would like some more
information to help track down why this is happening. In addition, could
you post information about your graphics accelerator? You can find this in
ParaView's About dialog available through the Help menu.

Thanks,
Cory

 Dear David,

 Do you have any further ideas on this axed grid visibility problem? I
 still have the problem. One more screenshot on a 2d model is attached.

 BR,
 Umut
