Abstract

In this contribution, we present the simulations of convective plasma cells of the Sun in two dimensions. With a simple stream function, it is possible to visualize multiple n × n convective cells. To obtain the simulation, we solve the magnetic diffusion equation with a fourth order scheme. Some applications for this simulations are also presented.

Keywords: plasmas; MHD; computer simulation.

Resumen

En esta contribución, presentamos las simulaciones de células de plasma convectivo del Sol en dos dimensiones. Con una función de flujo simple, es posible visualizar múltiples celdas convectivas n × n. Para obtener la simulación, resolvemos la ecuación de difusión magnética con un esquema de cuarto orden. También se presentan algunas aplicaciones para estas simulaciones.

Palabras clave: plasmas; MHD; simulaciones por computadora.
