[Paraview] Highlighting specific nodes as a function of time

[Pradeep Jha]

Dear Samuel San,

thank you for the response. But it didn't answer my question. I have a grid
of 512x512x512 which I initiate in the xmf file using the following lines:
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
      <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>
      </Geometry>
      <Time Value="00006"/>
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
In this geometry I want to visualize just ONE coordinate at each time step.
Suppose I want to have a little sphere at (x*,y*,z*) for time = t, how do I
edit the xmf file to do that? How should I input that data?

I hope I explained my question clearly. If not, please let me know.
