= ISSDE Overview [http://lanseyilin.com:8000/trac/wiki/WikiStart 中文版] ISSDE Monte-Carlo full-orbit-following program is based on the stochastic equivalence of Fokker-Planck equation and Stratonovich SDE. Stratonovich SDE is divided into deterministic part and stochastic part by splitting the dynamic system. The deterministic part is solved by the volume-preserving algorithm, and the stochastic part is discretized by the midpoint scheme according to the requirements of the Euler-Maruyama numerical method and the definition of the Stratonovich integral, and then solved by the quasi-Newton method. The correctness of ISSDE has been verified by the analytical solution of FP equation, and the corresponding results for electron-electron collision process are also consistent with the physical process. Compared with the stochastic Runge-Kutta method, the ISSDE can limit the numerical error of the conservative system energy to a very small range. ISSDE has been used to study fast ion loss and slowing down in EAST. == Basic framework of ISSDE * [http://lanseyilin.com:8000/trac/wiki/theory_Eng Basic theory] * [http://lanseyilin.com:8000/trac/wiki/user_page_Eng User's manual] * [http://lanseyilin.com:8000/trac/wiki/code_page_Eng Development Manual] * [http://lanseyilin.com:8000/trac/wiki/vocabulario_Eng Related vocabulary] == Project related * Contact us: yifeng.zheng@ipp.ac.cn * Project numbers: Tink Zheng == Links * [http://www.lanseyilin.com/wordpress/?page_id=168&lang=en Interesting Simulation]
