Abstract
Magnetostatic methods that are used for the nondestructive evaluation of ferromagnetic materials can be modeled by partial differential equa tions. Conventional numerical methods such as finite difference, finit e elements or boundary integral methods for large problems typically r equire an iterative matrix inversion scheme to solve the system of equ ations. Parallel implementation of such schemes is extremely difficult due to the data dependencies inn the matrices. Monte Carlo methods of fer an alternative approach by reducing the differential equation to s imple, independent, random processes that are inherently amenable to p arallel implementation. This paper investigates the use of Monte Carlo methods for modeling magnetostatic flux leakage NDE phenomena. The mo del is validated by comparing the results with those obtained with fin ite element models. The approach offers significant reduction in compu tational burden especially for 3-D problems.
