Recently, researchers have investigated parallel solvers for integral or differential formulation of Maxwell's equations. The electric field inside human tissues has been calculated by means of the numerical solution of Laplacean partial differential equation. Non uniform mesh was applied and parallel numerical algorithm was proposed in order to speed up the solution. A three-dimensional finite difference (FD) model of biological tissue around sacrum bed sore in human has been studied. Superposed electric field in biological tissues due to exogenic electric stimulation below knee leg was numerically calculated by means of finite element (FE) model. Geometry of models is based on anatomical data. Electric properties of tissues are obtained from the data available in references. Non homogeneous and anisotropic electric properties of living tissues were considered. In addition (FE) model of below knee leg has been numerically calculated and analysed. The proposed large-scale three-dimensional models was found to be an effective tool for analysis of electrical field distribution inside biological tissues. In order to compare calculated results the electromagnetic field intended for various purposes typically used in clinical practice was reviewed regarding to relevant references.
