[Paraview] Read EnsightGold with different timesteps

[Braun Fabian]

Hi all,

As I haven't yet received a reaction onto my previously reported problem on crashing ParaView when reading EnsighGold *.case files (see email below) I would like to enquire again if no one has a solution to this problem or at least is aware of this as a known bug? 
I would be happy to share my EnsightGold files in order to solve this problem...

Additionally, I have another similar issue where I have again EnsightGold files which hold 5 time steps of a 3D surface mesh whereas for this mesh only the node coordinates but not the mesh connectivity do change over time ("change_coords_only" option in .case file). Even though the ens_checker validates these files successfully, ParaView does not seem to be able to cope with this scenario. 
When loading the .case file the mesh of the first time step is visualized properly. However, when one changes the time to any of the following time steps no more mesh is visible and the statistics inspector reports 0 everywhere (No. of Cells/Points, Memory, etc.).

Any idea on how to tackle these two issues? 
(For me the first issue - in the email below - is the more interesting one)

Thanks a lot for your hints in advance!
Best wishes,
Fab

Dear all,

In order to nicely visualize a dynamic 3D model I want to use ParaView in combination which EnsightGold (*.case) files. My tetrahedral FE model has a static geometry and only one variable of the elements (scalar per element) is changing over time.

To this end I created three files: (1) example.case, (2) example.geo, (3) example.sigma. The latter is holding all timesteps of the dynamic variable (in my case the conductivity).
Furthermore, I've verified these files using the ens_checker application which concludes with a positive "Hooray! Data format verification SUCCESSFUL with No Warnings".
However, if I load the casefile in ParaView only the first timestep can be visualized. As soon as I change the time to another timestep ParaView freezes (no more reaction and consumes 100% of CPU).

Is it possible that what I want to do using the EnsightGold files is not supported by ParaView?
What else would you suggest me to resolve this problem?

Thank you very much for your help in advance.
Best wishes,
Fab

PS: I am using ParaView 4.3.1 on a Win 7 64-bit machine
PS2: A hint which might be useful for others looking for the ens_checker application: I simply downloaded the current trial version of Ensight, opened the executable of the setup in an archive manager (e.g. 7-zip), located and extracted the ens_checker.exe.
