Coupling of nonconforming finite elements and boundary elements. II: A posteriori estimates and adaptive mesh-refinement
The authors have established the coupling of nonconforming finite element and boundary element methods in Part I [ibid. 62, No. 3, 229-241 (1999; Zbl 0946.65121)], where quasi-optimal a priori error estimates are provided . In this second part, they establish a posteriori error estimates, and the corresponding adaptive mesh-refinement algorithm and its implementation is outlined. Two numerical examples illustrate the efficiency of the adaptive coupling scheme.
