The height of the power transmitting towers is usually in the range of 10m to 40m and the separation between two consecutive towers is about 200m to 400m. In addition, the area of the ground that needs to be considered in the simulation is large. Therefore, Finite Element Method (FEM) is not suitable for simulation of this application. Whereas Boundary Element Method (BEM) is best suited for these open region problems. This paper refers to the 3D Electric Field Solver COULOMB™ for the simulation method and presented results. The BEM method is based on the discretization of Maxwell’s equations in integral form. BEM’s distinctive strength lies in its ability to achieve a high degree of precision both locally and across the entirety of the problem domain. Though the BEM method is suitable for open region problems, it requires a computing machine with large RAM and CPU power to obtain a...
