[OpenWalnut] tensor line integration

[Francisco J. Beron-Vera]

Hi,

Let x denotes position on D \in R^2 and T(x) is a (symmetric) 2-tensor 
field on D. Then

(1) T(x) e(x) = \lambda(x) e(x)

where (e(x),\lambda(x)) is an eigenvector field/eigenvalue field pair. 
Then consider the ODE

(2) x'(s) = e(x(s)), x(0) = x_0,

where s is the natural parameterization (arclength).

I need to compute the integral curves of (1) - tensor lines. I have a 
table of numbers specifying the components of e on a regular lattice. 
How can do this computation using OpenWalnut?

Thank you in advance.

Francisco
