[Paraview] Python Scripts and memory

[Berk Geveci]

Hi Olaf,

Given that there is no memory management in your code, it is not surprising
that it leaks :-) One option is to use Delete() to get rid of objects after
using them. There is a short section talking about it here:
http://paraview.org/Wiki/ParaView/Python_Scripting

The even better approach would be to create the pipeline and all the views
only once and then simply update the filename in the loop. That would
guarantee that all resources from a previous timestep are released when the
 next one executes.

Best,
-berk
