Small question regarding this, how does this work for LAGRANGE_VEC variables. If u has components u1 u2 and u3 are these arranged in order or are they arranged the same way as u,v and p are arranged. I am also unsure how to add terms into the element force vector and the element matrix? Does the += operator automatically take into account the fact that there are multiple components? Thanks,
