The algoritm of currents calculation for particle-in-cell method

The effective algorithm for calculation of charge and current in the framework of method particle-in-cell (PIC) was developed. For calculation of currents the modified local conservative accelerated algorithm of macroparticles was used. The variant of smoothed influence function, which has small region of influence, was suggested. The region of influence is key idea in the method of local space-time decomposition (LSTD), which is used in parallelization of PIC codes. The application of algorithm of currents calculation is discussed for construction of 2D case of LSTD algorithm.
