Analytical Construction of Uniformly Convergent Method for Convection Diffusion Problem
In this paper, we study the uniformly convergent method on equidistant meshes for the convection-diffusion problem of type;
where the formal adjoint operator of L.
Lu=-εu''+bu'+c u=f(x), u(0)=0, u(1)=0
At the end of the this paper we will generate the scheme;
-e^(ρ_i )/(e^(ρ_i )+1) U_(i-1)+U_i-1/(e^(ρ_i )+1) U_(i+1)=(f_i-c_i U_i ) h/b ((e^(ρ_i )-1)/(e^(ρ_i )+1))
