Course

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.
