Topic: OOFEM 2.3 has been released

The official release of OOFEM 2.3 is now available. New features include:

        * XFEM support for cracks in 2D including branch functions and coupling of cohesive zones with XFEM.
        * XFEM elements: TrPlaneStress2dXFEM (new) and PlaneStress2dXfem (major modifications).
        * Support for Sets: Useable for boundary conditions, cross-sections.
        * FE^2 support for incompressible fluids with Dirichlet, Neumann and periodic boundary conditions.
        * Support for material orientations in layered cross section.
        * Improved support for directly using OOFEM from within custom applications.
    * Improved model for cement hydration.
    * A new isotropic damage model for tension/compression based on Griffith's solution.
    * VtkXml outputs at integration points.
    * Added variable cross section model.
    * New DKT plate element and plane stress element with vertex rotations.
    * New wedge elements for structural analysis.
    * Improved generic geometric non-linearity, many elements are now supported.
    * New options in nonlocal integral models - modified averaging operator based on the distance from the boundary or on the stress state.
    * Added new anisotropic damage model.
    * New linear constraint boundary condition.
    * Many bug fixes, small enhancements and documentation updates.
