Abstract
Programming in pictures is an approach whereby pictures and moving pictures are used as super-characters to represent features of computational algorithms and data structures, as well as to explain models and application methods involved. ∗AIDA is a language supporting programming in pictures. In this paper, a fluid dynamics problem is considered and an example of a ∗AIDA program for fluid flow simulation is provided. The program is presented as a set of information resources oriented not only to the executable code generation, but also to an explanation of the problem and its application algorithm. Various features of the ∗AIDA program are discussed and some comparisons with a Fortran equivalent are performed.
