Z. Dostal et J. Malik, SYMMETRICAL FE-BE COUPLING WITH ITERATIONS ON THE INTERFACE, International journal for numerical methods in engineering, 38(1), 1995, pp. 27-35
The paper presents an algorithm for the solution of problems that are
discretized partly by the finite element method and partly by the boun
dary element method. The algorithm is based on the conjugate gradient
method with preconditioning by an auxiliary conjugate projector that r
educes the iterations to the interface. A numerical example is present
ed to illustrate the performance of the algorithm. The method may prov
e useful also in parallel environment.
