Very small timevalue are skipped by the vtkEnsightReader
There is a limitation in Paraview's Ensight reader.
If, in a given simulation, time step of very different size are use: some time step of order 10e-5 second and some of order 1 second, the Ensight reader will fail to correctly load all the time steps. This limitation might be caused by the time steps values in the ".case" file being read in "single precision".
This issue was created after some discussion on the Paraview forum. Details about the problem are discussed here : Paraview forum
Thank you Jean-Philippe
