“…The possible structure of this relationship, as well as its interpretation, is largely determined by the structure of a specific GCE and the content of the tasks of analyzing its results that the researcher faces. However, we can consider general relationships that can be used to describe and analyze a wide class of computational experiments [7][8][9][10]. The following two situations can serve as examples of such relationships:…”

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 immediately for a certain class of mathematical modeling problems specified in a multidimensional parameter 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 metaphor that defines a visual map prototype. A description is given of a software system for constructing and analyzing three-dimensional visual maps of a generalized computational experiment. The paper also considers examples of its application in estimating the accuracy of numerical models of the OpenFOAM software platform for a three-dimensional problem of inviscid flow around a cone.

This paper continues the 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 the application of visualization and visual analytics methods. A generalized computational experiment implies a multiple solution of the numerical simulation problem for different sets of values of defining model parameters, and such an approach allows for obtaining a solution at once for a certain class of problems of mathematical modeling given in a multidimensional space of defining parameters. The paper considers an extension of the existing author's approach to the construction of visual maps of the generalized computational experiment, based on the application of visualization metaphors that can display not only individual images, but also their relationships. A method for constructing visual maps of a generalized computational experiment is proposed, which is focused on visualizing relationships between single computational experiments in threedimensional space. The method is based on the mechanism of formalization of relations between single computational experiments, as well as on the notion of a graph model visualization metaphor, which defines a prototype of a visual map. A description of the software system for the construction and analysis of three-dimensional visual maps of a generalized computational experiment is given, and examples of its application in assessing the accuracy of numerical models of the OpenFOAM software platform for the three-dimensional problem of inviscid flow around a cone are considered.
