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.

AGM 3D creates the finite element meshes and manages all data necessary for the calculations. Its main purpose is the refinement of the mesh according to the refinement algorithm described in [Bey95]. Consequently only problem dependent parts such as the mathematical model or error estimators have to be implemented. The manual of AGM 3D [Bey94] describes all problem independent features in detail. Hence, this manual describes only extensions and new features.
