A comparison of two formulations to blend finite elements and mesh-free methods. (English) Zbl 1059.65104
Summary: Mesh-free methods have since their early developments been blended to the finite element formulation in order to benefit from the advantages of both numerical techniques. In this paper, two recently proposed formulations to couple mesh-free and finite element methods are discussed and compared.
