Physics AUC, 2012•cis01.central.ucv.ro… Trapping phenomena in fusion plasma models are studied also by the decorrelation
trajectory method [2]-[5]. In this paper we present some information about the numerical
codes used in the calculations related to the physical models (see eg [6]-[11]) based on
decorrelation trajectory method. Because these numerical codes have considerable length
we will only give information about their structure, the main idea and short information about
the parallelisation scheme used for the determination of the diffusion coefficients. …

Abstract
We presented some codes details based on Runge-Kutta-Fehlberg 45 (RKF45) method for the calculation of different global Lagrangian quantities specific to Langevin equations that characterize the diffusion in tokamak plasma.
