Grid Refinement - VTK Visualisation

Hi everyone,

I did a simulation with a grid refinement and I managed to give out a vtk file for each level. Now I would like to join these vtk files or visualize both of them at the same time.
Has anyone already tried that and knows how to solve this problem?

Thanks for your help.



I have found a very simple way to do so in the case of 2D vtk files:

  • Open all your files
  • Do a GroupDataSets filter over each one
  • Do a Threshold filter over the grouped data set and take the lower threshold
    to be a really small number but bigger than 0.

In this way you can visualize the complete picture of what is happening with your simulation.

With 3D vtk files it works straight out of the box.
