Extending the application domain of the model order reduction method in calculating the electrostatic field
A problem of determining the electrostatic field formed by a set of charged electrodes has been considered. The details of the approximate solving of the Dirichlet problem have been given for the Laplace's equation in a substantially spatial formulation based on the use of the model order reduction method. The mathematical models have been improved and the problem of calculating the electrostatic field has been simplified, taking into account the present symmetry of electrodes positioning in electronic optics systems. For the eighth-order abstract group, three independent structures of t
