A new interactive graphic user interface and mesh generator for 3D TWT collector analysis

Simulators for electromagnetic analysis of TWT collectors require manipulation of a large amount of information both in the input and in the post-processing phases. Efficient, user-friendly interfaces greatly enhance the design capability of these tools by guiding the designer through a step by step process, during which full control of choices is kept and correctness of input information is assured. In this paper the authors intend to present a new dedicated interactive Graphic User Interface (GUI) which includes an automatic mesh generator, designed for the COCA simulator, a novel 3D FE tool for TWT collector analysis, developed at the University of Catania under an ESA/ESTEC project. Differently from other interfaces, dedicated only to result restitution, the Graphic User Interface of COCA aims at facilitating the management of all the various aspects of a simulation session. These range from input of geometries for the FE mesh generation to FE model processing and output postprocessing. The mesh generator has two operation modes a dedicated deterministic one and a neural one. The neural mode generates meshes which evolve from an initial simple configuration in such a way to approach a user-defined mesh density in critical regions.
