摘      要：The artificial boundary method is applied to solve three-dimensional exterior *** kind of rotating ellipsoids are chosen as the artificial boundaries and the exact arti-ficial boundary conditions are derived explicitly in terms of an infinite *** thewell-posedness of the coupled variational problem is *** is found that error esti-mates derived depend on the mesh size,truncation term and the location of the *** numerical examples are presented to demonstrate the effectiveness andaccuracy of the proposed method.
