Can the latest version of the extended finite element model consider hydraulic fracture propagation in natural fractures?
Dear friend Qiang Wang
The extended finite element method (XFEM) is a numerical technique used to simulate the behavior of materials and structures with discontinuities, such as cracks and fractures. While the latest version of XFEM has advanced capabilities, the ability to consider hydraulic fracture propagation in natural fractures depends on the specific implementation of XFEM being used and the characteristics of the natural fractures in question.
XFEM can be used to simulate hydraulic fracturing in a variety of settings, including those with natural fractures. However, accurately representing natural fractures in a simulation requires a detailed understanding of their geometry, orientation, and mechanical properties, which can be challenging to obtain in practice. Additionally, accurately modeling fluid flow through complex fracture networks can also be computationally intensive.
There are several studies that have utilized XFEM to simulate hydraulic fracture propagation in natural fractures, and some have shown promising results. However, the accuracy of the simulation depends on the assumptions and simplifications made in the model, as well as the input parameters used.
Thank you very much for your answer. I would also like to know whether the extended finite element in abaqus can be simulated when two or three natural fracture geometry parameters are known.
