Values of the second derivative of a TimeFunction

[AMzaheri]

I’ve been trying to calculate the second derivative of a TimeFunction as follows:

Image1 = TimeFunction(name='image', grid=model.grid, space_order=2) op = Operator(Eq(image1, image1.dx2)) op.apply(time=0) Could someone tell me if I’m right please? If so, I was wondering how I can have access to the values of the second derivative.

Thank you,
