Great, thanks for the follow up.

Re: [Paraview] Given 2D Displacement Field, Visualize Stretch as Geometric Change in Mesh

Charlie,

You can use the Warp by Vector filter to warp the points in your data
set according to a vector field. To get that vector field from your
p_x and p_y scalar arrays, it is convenient to use the Python
Calculator with the expression

make_vector(p_x, p_y, np.zeros(p_x.shape))

Apply the Python Calculator filter to your data set, then add a Warp
by Vector filter off the Python Calculator filter. Set the Vectors
property to "result", the default name of the array produced by the
Python Calculator.

Hope that helps,
Cory
