A

mesh
...
is
...
a
...
network
...
of
...
line
...
elements
...
and
...
interconnecting
...
nodes
...
used
...
to
...
model
...
a
...
structural
...
system
...
and
...
numerically
...
solve
...
for
...
its
...
simulated
...
behavior
...
under
...
applied
...
loading.

First,
...
computational
...
techniques
...
create
...
an
...
analytical
...
model
...
by
...
populating
...
the
...
material
...
domain
...
with
...
a
...
finite-element
...
mesh
...
in
...
which
...
each
...
line
...
element
...
is
...
assigned
...
mathematical
...
attributes
...
(axial,
...
bending,
...
shear,
...
and
...
torsional
...
stiffness,
...
etc.)
...
which
...
simulate
...
the
...
material
...
and
...
geometric
...
properties
...
of
...
the
...
structural
...
system.
...
The
...
system
...
is
...
then
...
...
within
...
boundary
...
conditions
...
and
...
subjected
...
to
...
mechanical

or

thermal

loading. 
Numerical solution may then resolve structural stresses, strains, and displacements.
The SAPFire ® Analysis Engine drives the meshing and numerical-solution procedures of Software. A multi-threaded solver takes advantage of current multi-core CPU systems, and can utilize more than 4 GB of RAM. This enables sophisticated and efficient meshing techniques which automatically translate the user-defined object-based model into a finite-element model. Analysis, design optimization, and useful output information all proceed automatically through a streamlined and powerful computational process.
Notable meshing features include the ability to:
- Coordinate tessellation with object orientation.
- Observe material boundaries to establish effective aspect ratios.
Tips
- Mesh size should be decreased through a series of analysis iterations until two subsequent sets of results are similar, or until the balance between accuracy and analysis time are acceptable according to engineering criteria.
