 ======Step 2======
-Once the velocity gradient vector is computed, use the <code>Python Calculator</code> filter. In the box labeled expression, type <code>eigenvalue(strain(Velocity)**2 + (Gradients - strain(Velocity))**2)</code>. Note that your velocity field may not be called Velocity. If this is the case, change the aforementioned formula accordingly. Also, I recommend calling the Array name <code>lambda</code> opposed to the default <code>result</code>.

The lambda_2 values will be the entries in the second column of this computed vector.
