  • In this work, we propose incorporating the finite cell method (FCM) into the absolute nodal coordinate formulation (ANCF) to improve the efficiency and robustness of ANCF elements in simulating structures with complex local features. In addition, an adaptive subdomain integration method based on a triangulation technique is devised to avoid excessive subdivisions, largely reducing the computational cost. Numerical examples demonstrate the effectiveness of the proposed method in large deformation, large rotation and dynamics simulation.
