摘　　要：针对豪华游轮,开发了结构化网格自动生成软件SUGOT-LCS。模型导入、计算域划分、网格生成和设置边界条件等操作均可自动完成。以一艘豪华游轮模型为例进行校验,并生成4套网格就阻力性能和自由表面波高分布对网格的依赖性进行了考察。计算结果表明,该方法可显著节省网格生成的时间,而且采用粗网格进行阻力性能预报已具有足够的精度,可将其应用于船型优化,具有较强的实用性。A structured grid generation software SUGOT-LCS is developed for luxury cruise ships.Operation of importing the hull,dividing computational domain,generating grid and setting boundary conditions can be automatically completed.A luxury cruise ship is used as an example to verify the software,and four sets of grids are generated to investigate the dependence of the resistance performance and the free surface wave pattern.The results show that the method can significantly save the time of grid generation,and the prediction of resistance performance using coarse grids has enough accuracy.This method can be applied to hull form optimization and has strong practicability.
