Abstract

The algorithms of numerical simulation of multi dimensional electromagnetic fields and PIC models for particles have been described. A new approach to generation a boundary-fitted curvilinear mesh based on five-parameters representation of mapping the complex-shape physical domain to a set of rectangular blocks is used. This algorithm permits us to construct a fast and universal mesh generator with flexible management with mesh parameters, condensing the mesh knots near edges and in subdomain with high gradients of solution. This way is able to reduce the total number of mesh knots in many times in compare with using a regular rectangular mesh. The codes with Poisson and Maxwell solvers have been implemented, those use as finite-difference as boundary- element methods. The results of this technique are demonstrated for simulation 2D and 3D problems.
