改写下面这句话：网格的第一层需要布置在次粘合层上y+应该相对较小。对于模拟的网格y+大部分在1左右满足了强化壁面处理的要求。

The first layer of the grid should be placed on the sub-adhesive layer, and y+ should be relatively small. For the simulated grid, most of the y+ values are around 1, which meets the requirements of wall reinforcement treatment.

Rewritten: The initial grid layer should be positioned over the sub-adhesive layer and maintain a relatively small y+ value. In the simulated grid, the majority of y+ values hover around 1, satisfying the criteria for reinforced wall treatment.
