Geometry and simulation modeling in design languages

In this third paper of the series [1], [2] about satellite design languages, the detailed geometry and simulation modeling is described. The definition of the FireSat subsystems in different design languages is presented in the first paper. In the second part, novel analytical design evaluations resulting from these means are shown. This paper focuses on the detailed simulation models that can be generated out of the design languages. These simulation models provide the means to solve the field problems based on differential equations in the specialized engineering applications. From an abstract geometry description the design languages can be exported in different computer aided design tools (CATIA, OpenCascade, etc.). All models shown in this paper are entirely generated out of a description within the UML. The same geometry description is used for a thermal simulation of the satellite in the ESATAN thermal design suite. The third usage of the abstract geometry description is for the automated routing of the harness cables that is presented. As a non-geometric example for a simulation model, the behavioral simulation of the attitude control in a generated Matlab Simulink model is shown. All the information required to generate these models is organized in the different design languages.
