Description
Summary:The Monte Carlo technique has been effectively applied to eddy current problems. The proposed approach is based on the random walk idea of a particle moving about in a medium, and registering information upon contact with a boundary. The standard Helmholtz-type equation encountered in eddy current problems is solved by letting one particle become multiple particles in its walk through the problem. Application to a simple 2-D eddy current problem is presented. The solution was calculated at every point in a grid by a direct finite difference approach and by the Monte Carlo method. The results indicate that, on a data parallel system such as Maspar MP-1, the Monte Carlo method becomes competitive in CPU time as a total solution approach for problems involving more than 300 unknowns.< >
