For the vector functions
the Neumann boundary term (5.31)
is given by
![]() |
(C.35) |
Assuming that
is a constant scalar in each element the corresponding element matrix is given by
![]() |
(C.36) |
For the face
opposite to the node
(
):
The element function
is 0
on the element face
.
Thus the first row of the element matrix is zero.
![]() |
