Hi
I would like to animate the following data. I have mesh file in (*.vtk) format and I have the following ascii data (nodal displacements at different time steps) in a file.

Time Step 1:
Nodes Displacement X Displacement Y
1 .................................................. ........................
2 .................................................. ............................
3 .................................................. ...............................
.................................................. ...........................................
Time Step 2
1 .................................................. ..............................
2 .................................................. ................................
.................................................. .......................................
and so on.
My intention is to animate this nodal displacement data in ParaView. What is the data format required to achieve this? could anyone please tell me with a small example?

Thanks!
With regards
Vijayendra

Quick answer:

1. You need to save the displacements as a vector field, for each node of the mesh, even those that aren't moving.
2. When saving into VTK, each VTK file is relative to 1 time snapshot and should include the original mesh of the case. Which means that all VTK files have the same mesh.
3. Example on name format:
   

   snap00.vtk
   snap01.vtk
   snap02.vtk
   snap03.vtk

4. Some more details: http://www.cfd-online.com/Forums/par...-paraview.html
5. Then, after loading the VTK group "snap..vtk" in ParaView, you can apply the filter "Warp By Vector", which can be used for applying the displacement on all nodes by using the displacement field.
