摘要：
This paper presents a coupling method between a discrete element code CeaMka3D and a finite element code Sem. The coupling is based on a least-squares method, which adds terms of forces to finite element code and imposes the velocity at coupling particles. For each coupling face, a small linear system with a constant matrix is solved. This method remains conservative in energy and shows good results in applications.
