Abaqus 6.9 release has XFEM
Hi All,
The new Abaqus 6.9 release offers new capabilities for fracture and failure (XFEM) and much more. http://www.simulia.com/products/abaqus_fea
Release Highlights:· The Extended Finite Element Method (XFEM) has been implemented in Abaqus and provides a powerful tool for simulating crack growth along arbitrary paths that do not correspond to element boundaries. In the aerospace industry, XFEM can be used in combination with other Abaqus capabilities to predict the durability and damage tolerance of composite aircraft structures. In the energy industry, it can assist in evaluating the onset and growth of cracks in pressure vessels.· The general contact implementation offers a simplified and highly automated method for defining contact interactions in a model. This capability provides substantial efficiency improvements in modeling complex assemblies such as gear systems, hydraulic cylinders, or other products that have parts that come into contact.· A new cosimulation method allows users to combine the Abaqus implicit and explicit solvers into a single simulation—substantially reducing computation time. For example, automotive engineers can now combine a substructure representation of a vehicle body with a model of the tires and suspension systems to evaluate the durability of a vehicle running over a pothole.· A new viscous shear model allows the simulation of non-Newtonian fluids such as blood, paste, molten polymers, and other fluids often used in consumer product and industrial applications.
That's good news
Is there any other software has the xfem analysis ability?
X-FEM in Code_Aster
X-FEM has been implemented into Code_Aster, a FE analysis code which is free and open source:

thanks
good soft. i am interesting in pthon.
Is there any other 3D x-fem
Is there any other 3D x-fem source code except Code_Aster informed by Jean-Michel Pereira
XFEM in ABAQUS
Having difficulty in determing the value of stress intensity factor? how to determine it through XFEM?
