Simultaneous estimation of spatially dependent diffusion coefficient and source term in a nonlinear 1D diffusion problem

Rodrigues, F.A; Orlande, H.R.B; Dulikravich, G.S - In: Mathematics and Computers in Simulation (MATCOM) 66 (2004) 4, pp. 409-424

This work deals with the use of the conjugate gradient method in conjunction with an adjoint problem formulation for the simultaneous estimation of the spatially varying diffusion coefficient and of the source term distribution in a one-dimensional nonlinear diffusion problem. In the present...
