The paper describes the development of two program modules for numerical system for computing the special functions of wave catastrophes – “Wavecat”. It shows the process needed to formalize computing of two special functions on the ANSI C programming language with usage of program libraries provided by the described software. A set of new cross-sections was painted by the system for two catastrophes F4 and A1A2A1A1. A number of improvements for the software complex were proposed because of the necessity shown during of new program modules.

In the article, the author enlightens a question of development of the software for numeric modeling of SWCs, in particular ways of performance optimization used for various components of the system: the computing core and the contour-plotter component. Recent changes in the source code are overviewed, for example, the things related to caching SWC values in different points after calculation for future use in similar tasks, or a new possibility to setup the software to serve requests as a kind of distributed computing network.

This article shows the main architectural characteristics of developed сore software for computing special functions of wave catastrophes (SWC). Technical solutions applied during development and their preconditions are described in the article. The results of software design are analyzed and some future directions of improvement are observed. The materials contain information about used data structures and modular system. A component making the system multithreaded is also observed in the article.
