<br>
In the meantime I have found the problem with the binary ensight
gold reader.<br>
<br>
Whenever the variable-files are read for a time steps greater than
1, Paraview has to jump in the binary file to the desired
timestep. This is done by partially parsing and skipping blocks
until the correct "BEGIN TIME STEP" is found. In order to skip the
correct block length, Paraview uses the number of points (numPts)
from the current geometry step. This breaks with a varying number
of points per timestep.<br>
As an example my first step contains 2 points and the second step
6 points, therefore when Paraview skips the first time step, it
skips a block length equivalent to 6 points. The correct number
would be 2 points. It therefore skips past the next "BEGIN TIME
STEP".<br>
<br>
In order to verify my theory I have implemented a little hack
which looks for the next "BEGIN TIME STEP" by brute force. In case
someone wants to try this I have attached a patch which can be
used in conjunction with the examples in my previous mail.<br>
<br>
A clean solution would be to skip the correct number of points for
every given timestep. Unfortunately I do not have enough insight
into the Paraview/VTK ensight reader to implement this and would
appreciate any help in finding a clean solution to this.<br>
<br>
Cheers,<br>

I have problems when I try to visualize my results in Paraview
which include changing geometries. I can load the first time step
but when I switch to the next step (in which 4 points are added),
paraview freezes and htop shows 100% load for this process.
Surprisingly, this only happens when I use binary ensight gold
format. The same results written in ascii ensight gold format
work. The ens_checker tells me for both cases that I have valid
output files. Attached are the binary and ascii version of the
result. It would be nice to use binary output for my results.
<br>
<br>
I work on a 64 bit Linux system and I have checked out the latest
repository version of Paraview (but I have also tried older
versions: 3.14 and 3.6) giving me the same result.
<br>
<br>
Thanks in advance for your help.
