The now familiar consistency of loops
elements_1
and
elements_2
with embed-
ded
gauss_pts_1
appears again. The parallel (3D) version has the lumped mass
matrix for 20-node elements hand-coded in place of the
elmat
routine used in the
serial (2D) case which used 8-node elements. The time stepping loop involves compa-
rable loop
elements_3
while the pcg section involves comparable loop
elements_4
.
