A general approach to impose homogeneous boundary conditions on algebraic systems deriving from variational formulations of di!erential problems is presented. The proposed approach proves to be e!ective and its performances are particularly enhanced when sparse matrices are dealt with. It applies to
## Abstract This paper presents a novel radiation boundary condition (RBC) with the spectral integral method (SIM) to truncate the computational domain in the finiteβelement method (FEM). Because of the spectral accuracy of the SIM, the sampling density on the radiation boundary requires less than
