Official Release of OOFEM, version 1.7

The official release of OOFEM 1.7 is now available.
  • Added new solution algorithm for incompressible flow with SUPG/PSPG stabilization.
  • Added support for incompressible analysis of two immiscible fluids (including free surface flows) on a fixed domain in 2D, based on VOF approach.
  • Added new Direct Sparse Solver (contributed by R. Vondracek). Use --enable-dss when running configure.

For more information see the ChangeLog.

Official Release of OOFEM, version 1.6

The official release of OOFEM 1.6 is now available. A quick summary of the new features in this version:
  • Adaptive framework released. This includes new classes representing general error estimator, remeshing criteria and mesh generator interface. The adaptive linear and nonlinear static analyses are now available. True adaptivity with primary and internal variables transfer is supported.
  • Added new FM module (Fluid dynamic). It now includes CBS algorithm for incompressible transient flow analysis, constitutive model for Newtonian fluid, and linear 2d element with equal order velocity and pressure interpolation.
  • Implementation of MDM model (Anisotropic damage model).
  • Introduced new keywords in domain components size record! This includes ndofman, nelem, nmat, ncrosssect, nbc, nltf to identify number of domain components. See Input Manual for details.

For more information see the ChangeLog.

    Official Release of OOFEM, version 1.5

    A quick summary of the new features in this version:
    • Implemented serial and parallel interface to PETSC library
    • Linear and nonlinear static analyses can be run in parallel (requires PETSC support).
    • New mesage and error reporting. It support diferent log levels, filtering, multiple log objects, and counters for errors and warnings.
    • Improved and enhanced documentation.

    For detailed information see the ChangeLog.

20/05/2003

    Official Release of OOFEM, version 1.4

    Compared to the previous release (1.3) this new version has major enhancements in the following areas:
    • New tm module for solving transport problems. Current capabilities include stationary and transient (linear and nonlinear) analysis of heat and coupled heat and mass transfer problems for axisymmetric, two, and three dimensional cases.
    • Implemented general staggered problem, which allows to group basic problems together and to transfer and share the solution fields between basic subproblems.
    • Added new classes for FE interpolations and stress and strain vectors facilitating implemantations of new elements and material models.
    • Added interface to serial version of SPOOLES sparse direct solver (http://www.netlib.org/linalg/spooles/).
    • Improved parsing of input files. Non-relevant tokens are detected and reported.

    For detailed information see the ChangeLog.

10/12/2001

    Official Release of OOFEM, version 1.3

    Compared to the previous release (1.2) this new version has major enhancements in the following areas:
    • Redesigned the input data parsing. Significantly improved the checking of input syntax.
    • Implemented direct load/displacement control. The non-linear problem can be solved under direct control, indirect control, or their combination.
    • Implemented new efficient algorithm with significantly less memory requirements for internal structure allocation of coordinate based sparse matrices.
    • Added support for VTK data export.
    • Improved layer object removal and fixed the graphics flickering for several render modes in oofeg (post-processor).
    • New source directory structure.

    For detailed information see the ChangeLog.

06/06/2001

    The first public release of OOFEM, version 1.2 (under GNU GPL license) is available

10/08/2000

    • Added links to program features and gallery, summarizing the OOFEM capabilities and illustrating some results
    • Draft of Material Model Library Manual HTML (online) and PostScript. It describes the available material models and format of their input records.

08/10/1999

    EXTRACTOR tool available

    • Draft of EXTRACTOR Input Data Format Specification is now available in HTML (online) and PostScript. It describes the input file format for extractor package, which is a package for automatic extraction of user-defined values from OOFEM output file.

14/04/1999

    • Draft of POOFEM Input Data Format Extension Specification is now available in HTML (online) and PostScript. It describes the input file format extension for parallel analysis support.
    • Implemented parallel support for explicit dynamic computations. The parallelization is based on MPI message passing library. There are some interesting results available online.
    • There is t3d2oofem package available (written by Daniel Rypl). It converts T3d output to OOFEM input. The partitioning for parallel computations is supported and is done using METIS library.
