Getting Started

What is here

The source directory tree holds source code to the OOFEM package.

  OOFEM_TOP_DIR
  |
  |-- doc - contains the "User's guide", sources to generate "Reference manual", 
  |         documents describing the input file specifications, element and
  |         material libraries, and other useful documents. 
  |
  |-- src - source files of all oofem modules
  |   |
  |   |-- oofemlib - sources of the core part of OOFEM, the OOFEMlib module.
  |   |
  |   |-- sm       - sources of structural analysis module.
  |   |
  |   |-- tm       - sources of transport problem module.
  |   |
  |   |-- fm       - sources of fluid mechanics module.
  |   |
  |   |-- dss      - includes the sources for Direct Sparse Solver (DSS),
  |   |              contributed by R. Vondracek)
  |   |
  |   |-- main     - contains the sources of main() and implementation of some 
  |                  global functions for oofem, oofeg.
  |
  |-- tools   - sources for several utility programs.
  |
  |-- tests   - contains several tests, which are useful to verify
  |             the program functionality.
  |
  |-- bindings - holds sources to generate OOFEM bindings to Python programming language.

Pre-requisites

• The oofem requires the CMake cross-platform build system and C++ compiler with STL support (Standard Template Library).

• The oofem contains interface to IML++ library. It is the C++ templated library of modern iterative methods for solving both symmetric and non-symmetric linear systems of equations, written by Roldan Pozo. It can be downloaded from http://math.nist.gov/iml++/.

• Parallel support for distributed memory requires MPI library to be installed. If you do not have any, we recommend to use Open MPI. This is a freely available, high-performance, and portable implementation of MPI (http://www.open-mpi.org/).

• For high performance linear solvers, OOFEM can use PETSc, SuperLU, MKL Pardiso or Pardiso-project.org solvers.

• For high performance eigenvalue solvers, oofem uses SLEPc. The toolkit can be downloaded from SLEPc project home page (http://www.grycap.upv.es/slepc).

Installation

• unpack sources
• create an out-of-tree build directory

   mkdir -p ~/build/debug

• configure the target

   cd ~/build/debug; cmake PATH_TO_OOFEM_SOURCES

where PATH_TO_OOFEM_SOURCES is the path to OOFEM source directory, created in step 0 (~/oofem-2.2, for example).

• compile OOFEM

  make

Running the tests

To run the tests, go to your build directory and run ctest

ctest

Additional instructions

• Instead of cmake you can use ccmake which uses an ncurses interface, or cmake-gui for a GUI. Use the command make help for a list of all targets.

• You can find detailed installation (including installation on Windows) instruction on OOFEM wiki (http://www.oofem.org/wiki/doku.php?id=installation)

• To get support check out oofem wiki (www.oofem.org/wiki) and oofem forum (www.oofem.org/forum) as well.

Running oofem

The oofem program prints out the available options when run without any option. To run a specific job, you can enter

oofem -f input_file_name

Documentation

You may find OOFEM documentation here.
