I am solving the following equation:

K_11 * u_xx + K_12 * u_xy + K_22 * u_yy=M

The question is how to approximate the cross term in finite difference
in order to insure the solution is non oscillatory.

The 3-D equivalent has been solved with finite elements

: at page 10 and 11 of the paper. Just simplify for 2-D.
