What is QUAD-BUILD?
|

|
|
Quality quadrilateral mesh generation has always been a necessary
requirement in modern finite element analysis. The simplest way a meshing
task can be formulated is "to generate a mesh inside user-defined
closed sequence of line segments". But in reality the problem is
significantly more complex, due to the following fact: a real-life model
always contains at least one or several additional features processing
of which ultimately comprises up to 90% of the actual program code size.
Here are just several of possible features:
internal opening(s) of various shapes;
internal and/or boundary points that in FEM models correspond to
places where external forces or constraints are applied; such points are
often surrounded by zones where large stress gradients normally appear,
and therefore a very fine mesh must be generated in such zones in order
to provide trustworthy evaluation of stresses and strains;
the model boundaries, internal and/or external, may consist of a variety
of different entities, at least line segments and/or arcs;
inside the domain there can also be a large variety of line segments,
arcs and their complexly connected combinations, not necessarily
comprising closed sequences, but arbitrarily shaped instead;
real-life meshes may contain hundreds of thousands or even more
quadrilaterals, sometimes making it impossible or too long to generate
a mesh in reasonable time;
the user may also wish the program to automatically evaluate
initially imposed requirements for a desirable step size along each
entity, should those sizes turned out to be inadequate; for example,
too large.
QUAD-BUILD 5.0 possesses all the capabilities listed above. The user can also select several additional
options such as:
generation of QUAD8 and QUAD9 elements;
generation of large (compared to average size) elements inside the domain, thus
minimizing the total number of elements;
automatic renumbering of the model nodes with the goal of minimization
of the stiffness matrix bandwidth later at the FEA stage.
Over several years our company developed
a series of quadrilateral mesh generators
that would cover one or several of the additional features listed above.
The new product QUAD-BUILD 5.0 is significantly more powerful
than the earlier ones; it is applicable to many areas of
engineering that require accurate finite element modeling:
mechanical engineering,
electronics,
structural engineering,
to mention just a few. Below we provide a number of difficult to
create meshes that have been successfully generated by QUAD-BUILD 5.0.

Delivery, licensing and support.
|
|
|
QUAD-BUILD 5.0 is completely developed by our company and
contains no third party code. We wiil provide you with full, one-off
commercial licence and free support for 12 months. If you buy
QUAD-BUILD 5.0 we will provide you with:
- complete, fully commented source codes in ANSI C;
- the product's User Manual containing detailed descriptions of input and output data
structures and an example driver program;
- and a graphical visualisation program. It allows
displaying original domains that are to be meshed as well as generated
quadrilateral meshes.
Finally, our "try-before-you-buy" policy. If you send us
examples of your typical geometries, we will run QUAD-BUILD 5.0 and send you the meshes created. If you are satisfied with the results,
you can then buy QUAD-BUILD 5.0.
We invite you to contact us, preferably by e-mail on
comecau@ozemail.com.au or
comecauinfo@gmail.com. We can also help
you with other mesh generation, computational geometry and general finite
element analysis needs.
