Abstract
Presented paper describes a numerical study of discharge plasma motion. This non-stationary phenomenon with
steep gradients and sharp peaks in unknowns is described as a coupled problem of convection-diffusion equation
with source term for electron, ion densities and Poisson’s equation for electric potential. The numerical method
is 2nd order of accuracy in space and time and it uses dynamical adaptation of unstructured triangular mesh.
Results of numerical studies included size of computational domain, type of boundary conditions and numerical
convergence test are presented.
