time is not always the same as time-step. Here's an example of how you
could query the reader for time values and then use them
... nSteps = 0
steps = reader.TimestepValues
try:
nSteps = len(steps)
except:
nSteps = 1
steps = [steps] ...
anim = GetAnimationScene()
anim.PlayMode = 'Snap To TimeSteps'
anim.AnimationTime = steps[step]
view = GetRenderView()
view.ViewTime = steps[step] ... Render()

Hello,
My Data is of type h5 that I open using PFlotran HDF5 reader in
ParaView which are result of PFlotran simulation.
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.
If I try to interactively go to a certain time step and then save an
image, everything works fine.
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().
RenderView1.ViewTime = 0.0
RenderView1.CacheKey = 0.0
RenderView1.UseCache = 0
AnimationScene1 = GetAnimationScene()
AnimationScene1.AnimationTime = 0.0
WriteImage('myImage.jpg')
Render()
My timeSeries start at 0 and the python script works just fine for 0.
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:
RenderView1.ViewTime = 10000.0
RenderView1.CacheKey = 10000.0
RenderView1.UseCache = 0
AnimationScene1 = GetAnimationScene()
AnimationScene1.AnimationTime = 10000.0
WriteImage('myImage.jpg')
Render()
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.
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.
Thanks in Advance.
Hedie
