Discretization form of the continuity condition at the polar axis, with application to the gyrokinetic simulation in a magnetic fusion torus
Tiannan Wu, Zihao Wang, Shaojie Wang
A new computational method to solve the hyperbolic (Vlasov) equation and the elliptic (Poisson-like) equation at the polar axis is proposed. It is shown that the value of a scalar…
