We shall use the term ``computational science'' as a convenient shorthand
for ``computational science and engineering.''
A well-known characterisation of computational science activities was
presented by K. Wilson in 1986 . He summarized the
characteristics of computational science problems in whatever discipline
At that time Wilson also addressed a number of open issues
concerning computational science, all of which are still open issues
and will be addressed in the following sections.
- having a precise mathematical statement,
- being intractable by traditional methods,
- having a significant scope,
- requiring an in-depth knowledge of science, engineering or the
