I have developed a short OOFEM course (given at EPFL Lausanne, UPM Madrid, Universidade Nova de Lisboa). The main topics covered by the course include:

• Introduction: general structure and features of OOFEM, available resources.
• OOFEM structure: overall design, design principles, detailed description of the key parts and corresponding underlying philosophy: engineering model - numerical method frame, material - cross_section - element frame, interface concept. Special focus on code extensibility.
• Installation: pre-requisites, compilation, testing.
• Using the code: input data format, running the code, postprocessing.
• Practical section: depends on participant's interests - implementation of specific part (material model, element) into the code, practical sessions, etc.

• T3d: Mesh generator written by Daniel Rypl
• PETSc: Portable, Extensible Toolkit for Scientific Computation
• SLEPc: Scalable Library for Eigenvalue Problem Computations
• IML++: template library for numerical iterative methods
• MayaVi: a free, easy to use scientific data visualizer
• ParaView: Parallel Visualization Application
