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.
