Solids are eight-node
...
objects
...
used
...
to
...
...
3D
...
structural
...
systems.
...
Each
...
solid
...
has
...
six
...
quadrilateral
...
faces
...
with
...
a
...
...
at
...
each
...
corner.
...
Nodes
...
may
...
be
...
collapsed
...
to
...
form
...
wedges,
...
tetrahedra,
...
and
...
other
...
irregular
...
volumes.
...
An
...
isoparametric
...
formulation
...
offers
...
nine
...
optional
...
incompatible
...
bending
...
...
which
...
improve
...
bending
...
behavior.
...
Material,
...
temperature-dependent,
...
and
...
anisotropic
...
properties
...
may
...
be
...
assigned,
...
and
...
gravity
...
loads,
...
surface
...
pressures,
...
pore
...
pressures,
...
and
...
thermal
...
loads
...
may
...
be
...
applied.
...
Aspect
...
ratios
...
should
...
be
...
less
...
than
...
four,
...
while
...
those
...
near
...
unity
...
provide
...
for
...
the
...
best
...
results.
