Automatic adaptive generation of a coupled finite element/element-free Galerkin discretization
In this paper, we present the concept and the implementation issues for an adaptive coupling of the finite element- and the element-free Galerkin discretization. The present algorithm implemented within flexible data structure facilitates the automatic inclusion of meshfree zones and establishes the coupling between the zones with interface elements. The idea is to minimize the expense for a simulation based on a coupled discretization. Two examples at the end of this paper demonstrate the efficiency of the concept.
