文摘To calculate ship’s bydrodynamic by CFD-software,how to define the region is very important In order to found the 3D complex hull,the author chose Pro/ENGINEER’s powerful "curve" technology to do.In this paper,the author use analysis-method to evaluate the hull-surface,and based on the evaluation-value to adjust the surface,in order to make the surface lubricity.
