Despite significant efforts applied over recent years to development
of flexible and robust quadrilateral mesh
generation software, the complexities
of real-life problems lead more and more research in that area. Take
for example
a structural engineering model presented below. It is a combination
of rectangular subregions and
holes, so seems to be easily processed by an average
quadrilateral mesh generation application. However,
the reality is that the
actual mesh is far from regular, primarily because the original rectangular
components have different dimensions and are attached to each other
in a rather chaotic manner. This leads to the conclusion:
regardless of the actual shape of the model, a quadrilateral
mesh generation product designed for processing of general-case,
unstructured models, must be employed in the vast majority of real-life
cases. |
