Hi, Utkarsh,<br>
<br>
sorry I forgot to replay to the list. I wrote Marcelo yesterday<br>
"Dear Marcelo,
<br>
<br>
try Edit->Settings->Render View and disable "Use
Offscreenrendering for Screenshots".
<br>
The animation will take more time, but the memory ussage is constant
low.
<br>
We have the same problem when proccessing a large number of
timesteps in PV 3.12.
<br>
<br>
Best wishes,
<br>
Christian
"<br>
<br>
And he said now it's working fine.<br>
<br>
But in fact, this does not solve the real problem.<br>
I have a GTX580 GPU with NVIDIA 290.10 64bit proprietär driver and
the same memory leak when proccessing a large number of files
(>200 by fileseriesreader->vtkreader or my own liggghts plugin
reader).<br>
<br>
Can you please tell me how to check if OSMesa is used or not and how
to track down where the memory leak comes from (it is not the
reader) ?<br>
<br>
Thanks,<br>
Christian<br>

<pre wrap="">Marcelo,
Is this using OSMesa for offscreen rendering? There was a memory leak
in 3.10.0 that has been subsequently fixed when saving animations with
OS Mesa and offscreen rendering enabled.

<pre wrap="">
this is exactly the technique I use. Generate streamlines. Then
iso-contour the streamline object with the scalar field
"IntegrationTime". Use a single threshold. Then animate the threshold
value. Use Mode=Sequence, get a ramp between minimum time and maximun time.
Use Glyphs (small spheres or arrows) attached to the iso-valued contours
and they will "animate" their position along the streamlines.

Dear Jean Favre,
Thanks a lot, you showed me the way after a long search time!
I am facing a new problem now: when making animations, Paraview uses all
available memory then crashes (I am using Paraview 3.12.0 64bit). I just can
make about 400 frames before crashing. After producing the animation, I do not
know how to "flush" memory, since it remains busy.
Thanks a lot and congratulations for your job.
Best regards,
Marcelo Emmel
