“…Implicit structural modeling has traditionally been separated into two main classes [7,1]: (1) mesh-free methods [2,3,14,6,15,16,17,18] , and (2) mesh-based methods [4,19,5,7,8,20,21,22]. We also acknowledge an increasing interest in methods based on machine learning [23]. The method presented here is a mesh-based method, which starts by generating a mesh conforming to discontinuities such as faults [see 24,25,26,27,28, for suitable ⋆ Published in Computer-Aided Design, Vol.…”
