| Abstract: | A three-dimensional ray-tracing method for laser propagation in plasma and an algorithm of heat flow for electronic conduction are briefly described.A convenient calculation scheme for solving the non-equilibrium Pn equations is also presented.By using these methods and the newly developed LARED-H code,the two-dimensional simulations for the laser-irradiated gold disk and ring target are preformed.The reasonable two-dimensional behaviors of the target plasma are obtained. |

| Keywords: | three-dimensional ray-tracing limited flow heat-conduction two-dimensional simulation of disk and ring target |
