<font size="-1"><font face="Verdana">thanks for your feedback:<br>
We do use in-house FEM code which also use MPI: I will cross check your
suggestions. Small vtu work fine but 300mb one have problems (where it
is not obvious to manually check them). thank you again<br>

type="cite">What code are you using to write the .vtu files? Is it vtk
code or is it code that you wrote for your own simulation? It sounds
like it _might_ be incorrect values in the header parts of the velocity
field. I believe .vtu files are ascii so you should be able to hand
check the values that are being saved into the file with what you think
you should be writing.
<br>
<br>
Also on the off chance that your simulation is using either threads
or MPI or something where it is distributed are you locking the section
of code where the writing is performed? Possibly sounds like 2
processes maybe accessing and writing to the areas of memory as the
same ares is being written to disk.
<br>
<br>
Just some thoughts.

Paraview 3.4.0 replies with "...dataArray may be too short" in some
conditions.
<br>
<br>
the vtu are written under Linux 64 :
<br>
if reading whose vtu with client "windows 32" and server "linux 64" we
quite often have the message "...dataArray may be too short" from
Paraview 3.4.0. The same vtu file read locally under windows 32 is Ok.
<br>
Time to Time it is vice versa : the problem occurs under windows 32 and
run correctly under client/server.
<br>
If we mask the velocity field at loading it is working.
<br>
<br>
-Ascii mode sounds more secure even though it is not working 100% of
the cases.
<br>
-Finally, different vtu from a same run (at different time step) behave
differentely.
<br>
<br>
thanks to anybody having encountered those type of problem or who may
have some suggestions.
