Evaluation of a Numerical Model Using COMSOL Multi-physics Package

A number of computer program packages have been developed for the solution of the numerical methods. The main objectives of the paper were: to explore the benefit of computer program packages-that have been developed for the solution of problems based on numerical methods-in solving mathematical models, to solve the fundamental equations Laplace´s and Poisson´s equations which are known in mathematics as boundary value problems, and plot the voltage stress over a porcelain insulator-which represents a mathematical model - and to predict the power frequency breakdown voltages. Use was made of COMSOL/M package based on finite element method. It is found that the simulation and experiment results recorded in many studies are in close agreement. Thus, it may be concluded that the finite-element packages can be used with a fair degree of accuracy to design most of numerical models.
