Parallel efficiency of a boundary integral equation method for nonlinear water waves [PDF]
, 1997 We describe the application of domain decomposition on a boundary integral method for the study of nonlinear surface waves on water in a test case for which the domain decomposition approach is an important tool to reduce the computational effort.
