This paper addresses an important application of
machine learning (ML) in design. One of the major bottlenecks
in the process of engineering analysis by using the finite-element
method—a design of the finite-element mesh—was
a subject of improvement. Defining an appropriate geometric
mesh model that ensures low approximation errors and avoids
unnecessary computational overhead is a very difficult
and time-consuming task based mainly on the user's
experience. A knowledge base for finite-element mesh design
has been constructed using the ML techniques. Ten mesh
models have been used as a source of training examples.
The mesh dataset was probably the first real-world relational
dataset and became one of the most widely used training
set for experimenting with inductive logic programming
(ILP) systems. After several experiments with different
ML systems in the last few years, the ILP system CLAUDIEN
was chosen to construct the rules for determining the appropriate
mesh resolution values. The ILP has been found to be an
effective approach to the problem of mesh design. An evaluation
of the resulting knowledge base shows that the mesh design
patterns are captured well by the induced rules and represent
a solid basis for practical application. The aim of this
paper is not only to present the real-life ML application
to design, but also to describe and discuss a relation
of the work being done to the topic of this special issue:
the proposed “dimensions” of ML in design.
