- A novel approach for discrete fracture modelling using NURBS basis functions, suitable for brittle and cohesive fracture. NURBS yield vastly improved stress predictions, in particular around crack tips, and their flexibility is used here to locally lower the interpolation in order to capture discontinuities. The approach is augmented by an innovative hierarchical approach to mesh refinement and coarsening to further improve accuracy and efficiency. It is shown how this superior simulation technology can be implemented in commercially available finite element packages. It reports a crucial step of ERC Advanced Grant 664734 on modelling of fractures in porous media.
