Simulation of Needle-Type Corona Electrodes by the Finite Element Method

摘要

This paper describes a software tool,called LEVSOFT,suitable for the electric field simulations of corona electrodes by the Finite Element Method (FEM).Special attention was paid to the user friendly construction of geometries with corners and sharp points,and to the fast generation of highly refined triangular meshes and field maps.The execution of selfadaptive meshes was also implemented.These customized features make the code attractive for the simulation of needle-type corona electrodes.Some case examples involving needle type electrodes are presented.
