Generalized Computational Experiment State Analysis Using Three-Dimensional Visual Maps

The paper continues a series of publications of the authors' research materials in the field of developing an approach to dynamic planning and control of a generalized computational experiment based on visualization methods and visual analytics. A generalized computational experiment involves multiple solution of a numerical simulation problem for different sets of values of model defining parameters, which makes it possible to obtain a solution immediate-ly for a certain class of mathematical modeling problems specified in a multidimensional pa-rameter space. The paper considers an extension of the existing authors' approach to analysis of a generalized computational experiment state using visual maps, based on visualization metaphors that can display not only individual images but also their relationships. A method is proposed for constructing visual maps of a generalized computational experiment focused on visualizing relationships between single computational experiments in three-dimensional space. The method is based on the mechanism of formalization of the relationships between single computational experiments, as well as the concept of a graph model visualization met-aphor that defines a visual map prototype. A description is given of a software system for con-structing and analyzing three-dimensional visual maps of a generalized computational exper-iment. The paper also considers examples of its application in estimating the accuracy of nu-merical models of the OpenFOAM software platform for a three-dimensional problem of in-viscid flow around a cone. © 2022 National Research Nuclear University.
