- Numerical simulation has become a key element now strongly
integrated in product development cycles. It is therefore
crucial to be able to transform very quickly and reliably
a real-life geometry into a mathematical representation
usable by scientific software. It is also mandatory
to satisfy constraints such as low memory consumption,
or high mesh generation speed, in order to reduce considerably
the human effort necessary to exploit numerical simulation
in a conception cycle.
This constant search
for a reduction of costs naturally leads to considering
fast and quality solutions to speed up the mesh generation
step in a study. Today, more and more industrial scientific
software move towards tetrahedral meshes, not only
because it is the only way today to generate automatically
complex three-dimensional meshes, but also for some
particular reasons, such as:
- with tetrahedral
meshes, it is possible to model very accurately the
very complex geometries used in industry, and to do
so with a considerably reduced number of vertices.
- tetrahedral meshes are easily adaptable, locally
or globally, by taking into account for example complex
transient physical phenomena to capture, or a numerical
error estimator. It is therefore possible to obtain
a very fine solution with a limited number of nodes,
thus at a limited cost.
- tetrahedral meshes behave
better in terms of numerical error compared to other
element types when these elements are distorted, as
may happen in a context of time dependent geometries.
It is for these various reasons that Simulog and
INRIA have been working over ten years on tetrahedral
meshes, in order to provide the industry with a product
permitting an easy and quick generation of high quality
tetrahedral meshes: TetMesh (formerly known as GHS3D).
