The ADAPTIVE GRID MANAGER by Jürgen Bey provides a set of problem independent tools and a complete working environment for the adaptive numerical solution of partial differential equations in three space dimensions.

creates the finite element grids and manages all data necessary for the calculations. Its main purpose is the refinement of the grid according to the refinement algorithm described in section 3. Consequently only problem dependent parts such as the mathematical model or error estimators have to be implemented. The manual of describes all problem independent features in detail. Hence, the following sections describe only extensions and new features.
