Expressing the global force-matrix function can be simplified by using the compact notation:

$$\left [ K_ij \right ] \left \{ d_j \right \} = \left \{ F_i \right \}$$

$$\sum_{j=1}^6 K_ij d_j = F_i,\qquad i=1...6$$

How do you go from several local element matrices to one global matrix? An assembly plan! First you must identify the correspondence between the various elements and their degree's of freedom:
