| Abstract: | A numerical boundary condition about the surface density distribution is deduced from the continum equation by virtue of the integral character of the Finite Element Method(FEM).Numerical tests show that the present numerical boundary condition could be used conveniently in the viscous or the inviscid high speed flow calculation. |
