Cubic Jacobian
This function computes the Jacobian of the cubic component of the nonlinear internal force in global coordinates at the element level. The Jacobian is evaluated along the direction (x,y) and acted on the vector z. Hence, the output is a vector.
X = Assembly.unconstrain_vector([x y z]);
f3 = Assembly.constrain_vector(Assembly.vector('DF3',X(:,1),X(:,2),X(:,3)));
