This paper deals with electromagnetic field computations using distributed systems. Field problems given by Maxwell's partial differential equations are solved using well-established methods under given initial and boundary conditions. Spatial discretization performed by using the finite element method leads to linear systems of large dimension. Due to the large solution time, linear algebra methods are applied in parallel. Parallelism of conjugate gradient algorithm is considered and decomposition of computational domain amongst processors is discussed. It is focused on both load balancing and communication effort minimisation. An adaptive approach, based on recursive bisection, for load balancing is proposed and results obtained on a cluster of workstations are presented.
