广义涡旋方法应用于不可压缩、无旋转、无粘、分层流中自由表面运动的研究，其中波浪是由外部手段产生的，如淹没体的运动。开发了辐射条件，允许向外传播的波在没有明显反射的情况下逃离计算域。数值海绵层用于吸收向外传播的波。文中给出了由表面压力分布和水下物体平移产生波浪的应用。
Generalized vortex methods are applied to the study of free surface motion in incompressible, irrotational, inviscid, layered flows in which waves are generated by external means, such as the motion of submerged bodies. Radiation conditions are developed that allow outward-traveling waves to escape the computational domain without significant reflection. Numerical sponge layers are used to absorb outward-traveling waves. Applications are given to wave generation by surface pressure distributions and by translating submerged bodies.
