In this lesson, the development of finite element equations is continued, and the equations will be written in a matrix-vector form. The equations worked upon in this lesson are the same ones that were derived in the previous lesson during the finite element assembly. In the final equation, D vector and F vector terminology is defined.
The equation written in the previous video is written in a simpler form, and the final form is written. Remarks are made for the properties of the terms in the final form. The formal solution is shown for the actual field.
