Mesh files for WAMIT, NEMOH and HAMS

The dataset includes the mesh files for the simple truncated cylinder, the cylinder with heave plate, the incomplete cylinder and the overlapped cylinder, and the dataset is made available so the similar modelling results can be reproduced本数据集涵盖适用于简易截短圆柱、带垂荡板圆柱、不完全圆柱及重叠圆柱的网格文件（mesh files），并对外公开该数据集以实现同类建模结果的复现。
