TRANSIENT is a C program for solving arbitrary systems of generally nonlinear, parabolic partial differential equations in two variables (space and time), in particular, reaction-diffusion equations. An efficient adaptable time-stepping algorithm is applied. User has to supply a problem definition module (PDM) for each system of equations. A detailed 38 page manual (in the Latex form), and demonstration PDM's for four different problems are supplied with the package. One of the demonstration PDM's deals with the simulation of the uniform corrosion of a metal surface and the diffusion of the corrosion products into two consecutive adjacent porous media. This module uses a nonequidistant spatial grid in order to treat adequately (with an increased precision) the important region near the corroding surface.
