This thesis will cover how two applications were developed using the commercial software COMSOL Multiphysics. The first application, the Joule heating application, simulates joule heating while taking the skin effect into consideration. The second application, the Corona Discharge application, is used to simulate corona discharges. It also estimates the initiation of charge propagation using the integration of the Townsend mechanism. The goal of this thesis is to verify that the COMSOL Application Builder can be used to create easy-to-use applications. With a high degree of accuracy and efficiency, it aims to aid Hitachi’s work with the design and effectiveness of bushings. These applications were developed to have similar graphical interfaces, making it easier for users to understand their functionality. Although a striking similarity in the graphical interfaces, the two applications have vastly different computational formulas, and physical properties, and are not based on the same COMSOL modules. The applications resulted in improving Hitachi’s workflow by significantly increasing efficiency and accuracy. The applications also contain a high degree of guidance to help the user optimize their results. However, as with all code-based projects, there is room for improvement. In the case of the Corona Discharge Application, one upgrade could be to allow the application to automatically find and calculate points with the highest potential. In conclusion, this thesis found that it is possible to create applications based onCOMSOL models, with a high degree of accuracy and efficiency, while still making them easy to use, interactive, and retaining all their physical properties.
