[Paraview] ParaView Scripting

[Stefano Charissis]

Hi Sebastien,

Thank you for your recommendations.
I have already been through all those resources and I was not able to extract very much useful information from them. The the 'trace' suggestion seems promising. I can't quite get it to do what I want, but I'm sure it'll prove useful in the future.

This is what using the trace gave me:
--------------------------------------------------------------------------------------------------------
try: paraview.simple
except: from paraview.simple import *
paraview.simple._DisableFirstRenderCameraReset()

a3dResults_vtu = XMLUnstructuredGridReader( FileName=['/home/stefano/workspace/TestSimulations/3dpropagation/output/vtk_output/3dResults.vtu'] )
a3dResults_vtu.PointArrayStatus = ['V_000000', 'V_000001', 'V_000002', 'V_000003', 'V_000004', 'V_000005']

# From here, I don't even know how to do what I want to do manually
# At this point if I am in Paraview and I hit 'Animate' then it will animate V_00000 only. But, in fact, V_000000 is timestep 0 of V, V_000001 is timestep 1 of V, etc...
# So I essentially want it to either interpret the arrays as such or output a series of vtu files which I can then hopefully open 'together' (output*.vtu) and animate that...?
--------------------------------------------------------------------------------------------------------


Also. I would still like to know where I can look up the functionality of, for example, paraview.simple, for the future.

Stefano

Hi Stefano,

you can give a look at http://paraview.org/Wiki/ParaView and more precisely on:

http://paraview.org/Wiki/ParaView#Python_Scripting
http://paraview.org/Wiki/ParaView/Python_Scripting
http://paraview.org/Wiki/Python_GUI_Tools

Hope this could give you more insight... The trace can help you
convert UI interaction into script which can be manually tweaked for
your custom purpose.

Seb

The app outputs a single .vtu file which has multiple arrays, each representing the data at every time step of the simulation. I cannot animate this as it does not have any time information. I could not find the solution online and nor could I find any documentation for the python scripting. I tried that figuring that if I could seperate the vtu into multiple (ie. 0.vtu, 1.vtu, etc) then I could automatically produce animations.
