South Univ. (2020) 27: 842-852 DOI: https://doi.org/10.1007/s11771-020-4335-9 GF-3 data real-time processing method based on multi-satellite distributed data processing system YANG Jun(杨军......
accurately with conventional finite element method (CFEM) because it involves solid phase and liquid phase simultaneously. XFEM is becoming more and more popular with the need of solving the discontinuous problem happening in engineering field. The implementation method of XFEM is proposed on Abaqus code by using UEL(user element) with the flowchart. The key is to modify the element stiffness......
