中文摘要：

实现了一种船舶兴波阻力和兴波波形的数值计算方法，将CFD与CAD技术联系在一起，应用NURBS曲面造型技术将船体曲面表达为统一的数学模型，使性能计算的真实物面条件得以满足，应用高阶面元法数值模拟单、双体船在浅水航道中定常直航状态下的兴波阻力与兴波波形，并与瑞典ShipFlow软件的计算结果进行比较分析，表明该方法是可行的．

英文摘要：

This paper presents a numeric method about calculation of wave making resistance and wave pattern, which connects CFD with CAD technology tightly. NURBS technique is applied to forming the ship body by uniform mathematic model, so that true body condition can satisfy. The higher order panel method is applied to calculate wave making resistance and wave form about the ships sailing directly in the shallow water. The comparison about this method with the Swedish software ShipFlow shows that it is practicable.
