In this paper we present a numerical solution for the mathematical modeling
of the hot-pressing process applied to medium density fiberboard. The model is
based in the work of Humphrey[82], Humphrey and Bolton[89] and Carvalho and
Costa[98], with some modifications and extensions in order to take into account
mainly the convective effects on the phase change term and also a conservative
numerical treatment of the resulting system of partial differential equations.Comment: LaTeX, 11 figures. Added references. Fixed some errors. To appear in

Abstract. We present a numerical solution for the mathematical modeling of the hot-pressing process applied to medium density fiberboard. The model is based on the work of Humphrey (1982), Humphrey and Bolton (1989), and Carvalho and Costa (1998) with some modifications and extensions in order to take into account mainly the convective effects on the phase change term and also a conservative numerical treatment of the resulting system of partial differential equations. 2000 Mathematics Subject Classification. 65M60, 82C70, 76S05, 76T30. 1. Hot-pressing mathematical model. Hot pressing is the process in which a mat-tress composed of wood fibers and resin is cured by applying heat and pressure in a press (see Figure 1.1). Continuum and batch presses do exist, and one of the main issues in reducing the cost of the final product is to reduce the press cycle time. In order to improve the heat transfer between the press platens and the inner layers, some amount of water is added to the mat. Another issue is to adjust the parameters and the temperature history of the cycle in order to obtain a given density profile in the board. Normally, it is desirable to have lower densities at the center of the board i
