Abstract: A difference scheme for two-dimensional three-temperature energy equations in Cartesian coordinates is united with that in cylindrical coordinates.The LARED-H (laser radiation electron dynamic holehurm) code is extended to describe physical processes in both coordinates.Physical models are investigated for a line-focused target with different incident angles.Numerical results are given to describe the expanding process of target-plasma.

Key words: two-dimensional three-temperature energy equation, Cartesian coordination, cylinder coordination, planar target
