[Paraview] [EXTERNAL] Re: create a time sequence from a steady-state vector

[Scott, W Alan]

There is also an example of a programmable filter with eigenvalues on the tutorial page here:  http://www.paraview.org/Wiki/Python_calculator_and_programmable_filter.  Towards the bottom is a link to principleStrainPython.  

Hope that helps.

Alan
