@damienmarchal when the needle enters the FEM block, there is a Python exception:

[ERROR]   [Animation(unnamed)] Unable to execute code.
Python exception:
  ValueError: cannot resize this array: it does not own its data

At:
  needleInteractionTest.py(65): onAnimateEndEvent

Any idea what is going on?
