Re: [Paraview] Highlighting specific nodes as a function of time

Thu, 06 Jun 2013 07:57:45 -0700

Pradeep san,

ParaView is capable of reading multiple results inputs; they can be the same input read twice. The 2nd, 3rd, 4th, ... inputs can all be in different formats, the inputs can be displayed in the same view or separate views. A given input can be displayed in multiple views. A given input can be "moved" from one view to another using the eyeball toggle.

Does this help?

Sam

I think I can state my question much more simply. I have a file with data like this:

 00000,       241,          54,         310

 00054,      258,         369,           32

The first coloumn is the time stamp and the following three coloums are the x, y and z coordinates. I want to highlight the points in the file as function of time in a cube of 512x512x512 such that the only the particular node has a sphere (for example) and the rest of the domain is empty. 

How can I do that?

Hello,

I have a NxNxN (N=512) cube data stored in multiple h5 format files for a time varying solution. I read it in Paraview using a xmf file. I am able to make a time varying movie of a particular iso-surface using the xmf file.

For each time step I have a particular node, say (x*, y*, z*), which I want to highlight (using a sphere, for example). I have all these coordinates stored in a another file. Can anyone please suggest me, how can I make a movie where these particular nodes are highlighted along with the iso-suface movie?

Thank you,
Pradeep

My present xmf file looks like this:

<?xml version="1.0" ?> 
<!DOCTYPE Xdmf SYSTEM "Xdmf.dtd" []> 
<Xdmf Version="2.0"> 
  <Domain> 
    <Grid Name="Box" GridType="Collection" CollectionType="Temporal"> 
    <Grid Name="mesh1" GridType="Uniform"> 
      <Topology TopologyType="3DCoRectMesh" Dimensions="512 512 512"/> 
      <Geometry GeometryType="ORIGIN_DXDYDZ"> 
        <DataItem DataType="Float" Dimensions="3" Format="XML">0.0 0.0 0.0</DataItem> 
        <DataItem DataType="Float" Dimensions="3" Format="XML">0.1 0.1 0.1</DataItem>

    </Grid>

        <DataItem DataType="Float" Dimensions="3" Format="XML">0.0 0.0 0.0</DataItem> 
        <DataItem DataType="Float" Dimensions="3" Format="XML">0.1 0.1 0.1</DataItem> 
      </Geometry> 
      <Time Value="00006" /> 
      <Attribute Name="vor" AttributeType="Scalar" Center="Node"> 
       <DataItem Dimensions="512 512 512" NumberType="Float" Precision="4" Format="HDF"> 
        filename6.h5:/variable         
       </DataItem> 
      </Attribute> 
    </Grid>   
  ******many blocks like these************
    </Grid> 
 </Domain> 
</Xdmf> 


And the points I want to highlight have coordinates like this:

 00000       241          54         310
 00006       241          54         308
 00012       240          55         310
 00018       239          55         310
 00024       261         294         395
 00030       256         373          32
 00036       257         372          32
 00042       257         371          32
 00048       258         370          32
 00054       258         369          32
