Finite Element Method (FEM) has become the universal method for computing 2D potentials in rotationally symmetric electrostatic and saturated magnetic lenses, electrostatic multipoles and magnetic deflection coils inside lenses. For all these elements optimum methods for computing the first order FEM equations were derived, fast solution algorithms implemented and an option for accuracy evaluation of lens field added. Determination of the optical properties is complemented with high accuracy ray tracing which allows extracting the aberration coefficients of up to the 5th order from the ray-traced results.
