Dense magnetized plasma numerical simulations
The scope for developing the present numerical method was to perform parametric studies for optimization of several configurations in magnetized plasmas. Nowadays there exist several efficient numerical codes in the subject. However, the construction of one's own computational codes brings the...

The scope for developing the present numerical method was to perform parametric studies for optimization of several configurations in magnetized plasmas.
