A finite element (FE) perturbation method for computing electrostatic field distortions and electrostatic forces due to moving conductors is developed. First, an unperturbed problem (in the absence of conductors) is solved with the conventional FE method in the complete domain. Then, a perturbed problem is computed in a reduced region using the solution of the unperturbed problem as a source field. When the source is close to the perturbing regions, an iterative procedure may be required. The developed method allows for solving sub problems in reduced domains with independent problemadapted meshes.
