PENGEMBANGAN PROGRAM PEMBANGKITAN MESH TRIANGULASI ADAPTIF SEBAGAI DOMAIN MASUKAN ANALISIS ELEMEN HINGGA UNTUK PENYELESAIAN PERSOALAN TEKNIK MESIN UMUM
Abstrak: Finite element
method and its
applications have emerged
in engineering fields because primarily
its ability to give
approximation result that
could use as
data references for experiment and for
real systems. In this decade
the Finite Element Method is
important lecture in
technical especially in mechanical
engineering education.
The purpose of
this research is
developing the adaptive
triangulation mesh generation program
for input domain
of finite element
analysis to solve
general mechanical engineering problems. Research is conducted in some
steps. These are literate study, developing
the nodal distribution
program, developing the triangulation program
and developing the
adaptive mesh program.
Mesh is adaptive when
element densities could
be controlled to adjust
the gradient variations from
the result of
finite elements analysis
programs. Performance of adaptive
mesh could define
with minimum angle
criterion. This research
is conducted to proceed the previous research that have been
investigating structured mesh (Development of Adaptive Structured Mesh
Generation Programs as an Input Domain
for Finite Element
Analysis applied in
Elasticity and Composite,
2006) The results of this research are nodal distribution, triangulation
and adaptive mesh development program in simple manner. In general, outputs of
the mesh generation program are nodal coordinates and connectivity. Researcher
is developing running segment method to build the polygon triangulation. This
method is comparable with Delaunay triangulation method.
Nodal distribution is
underlined in this
research because of its importance to create adaptive mesh by h-method.
