SymFields: An Open Source Symbolic Fields Analysis Tool for General Curvilinear Coordinates in Python

Autor: Chu, Nan

An open source symbolic tool for vector fields analysis 'SymFields' is developed in Python. The SymFields module is constructed upon Python symbolic module sympy, which could only conduct scaler field analysis. With SymFields module, you can conduct

Alias Sampling Effect on the Calculation of MHD Mode Number in Fusion Plasma

Autor: Chu, Nan

Detailed alias frequency formula and the effect of alias sampling on the calculation of MHD mode number are derived. It is discovered that the absolute MHD mode number/structure does not change under alias sampling. This discovery can help us to dete
