<br>
Paraview can not open a Pixie file (it's a HDF5 format included through the VisIt Database<br>
Bridge) when the file includes one timestep only: Paraview just hangs indefinitely.<br>
Everything works fine when multiple timesteps are contained in the file.<br>
<br>
I suspect that the problem is connected to lines 618-634 in<br>

The condition is true not only when the same value (0?) has been assigned to all<br>
the timesteps but also when there is one timestep only (timesteps.size() = 1).<br>
Besides these lines were not present in Paraview 3.10/3.12 and these releases<br>
were able to open Pixie files containing one timestep only.<br>
<br>
Is it possible to fix this problem? That would be highly appreciated.<br>
