Simulation of the electric field in the many homogeneous mediums by charges simulation method

We develop a code of calculation of the electrostatic fields based on the method of the fictive charges (charges simulation method) in mediums containing simultaneously several dielectrics. Complex structures can be easily solved by a simple code. The great advantage of this method is the direct obtaining of the field without numerical differentiation of the potential. The geometry is obtained by use of autocad, then exported in a given file.
