<div>Hi Burlen,<br>
<br>
Thanks for your reply. Actually when I mentioned final
time step at 10000 to get the image; by 10000 I
actually was referring to the the time. ( The time
step related to this time (10000) is time step 40)<br>
<br>
</div>
I see what time is relating to what time step by using
the "AnnotateTimeFilter" and seeing the times
interactively.<br>
<br>
</div>
Considering that I know the correct time, still pvpython
crashes when I try to get the image at a different time by
changing the following to time=10000 or any other time
that exist in my simulation result.<br>
<br>
RenderView1.ViewTime = 10000.0<br>
RenderView1.CacheKey = 10000.0<br>
RenderView1.UseCache = 0<br>
AnimationScene1 = GetAnimationScene()<br>
AnimationScene1.AnimationTime = 10000.0<br>
WriteImage('myImage.jpg')<br>
<br>
Render()<br>
<br>
</div>
Any ideas on what I could be doing wrong and how to get the
image at a different time using pvpython ?<br>
<br>
</div>
I´d appreciate any help<br>
</div>
Thanks<br>

<div>Hello, <br>
<br>
</div>
My Data is of type h5 that I open using PFlotran
HDF5 reader in ParaView which are result of
PFlotran simulation.<br>
<div>
<div><br>
</div>
<div>What I am trying to do is to write an image
at a certain time step and then finally write
a batch job that writes an image for each time
step of the simulation result.<br>
<br>
</div>
If I try to interactively go to a certain time
step and then save an image, everything works
fine.<br>
<br>
</div>
<div>The problem is I have 40 time steps and I
want to do the same procedure often. So I saved
my state file as a python script and then set
these few lines at the end of script just before
Render().<br>
<br>
RenderView1.ViewTime = 0.0<br>
RenderView1.CacheKey = 0.0<br>
RenderView1.UseCache = 0<br>
AnimationScene1 = GetAnimationScene()<br>
AnimationScene1.AnimationTime = 0.0<br>
WriteImage('myImage.jpg')<br>
<br>
Render()<br>
<br>
<br>
</div>
<div>My timeSeries start at 0 and the python
script works just fine for 0.<br>
<br>
</div>
<div>If I change the following lines to 10000 (my
final time step) or any other time step, then
pvpython crashes, that is the following change
to the script makes the pvpython crash:<br>
<br>
RenderView1.ViewTime = 10000.0<br>
RenderView1.CacheKey = 10000.0<br>
RenderView1.UseCache = 0<br>
AnimationScene1 = GetAnimationScene()<br>
AnimationScene1.AnimationTime = 10000.0<br>
WriteImage('myImage.jpg')<br>
<br>
Render()<br>
<br>
</div>
<div>I used the trace to see what values I need to
change to save an screen shot for any time step
and I ended up with ViewTime and AnimationTime.<br>
<br>
</div>
<div>I have attached my script with this email. I
would be grateful if you could please tell me if
I need to change more in my script or add any
additional lines to be able to get an screenshot
of any timestep rather than 0.<br>
<br>
</div>
<div>Thanks in Advance.<br>
