snappyHexMesh的加密以及在直角处的边界层生成问题

[studentTan]

求教各位大佬，我在使用snappyHexMeshDict一个建筑的室内外网格进行加密的时候遇到了两个问题，首先是想通过控制level从（3,3）到（4,4）在壁面附近对网格进行加密，但是画出来的网格只有在拐角的地方有加密，平面区域没变；

没办法只能通过增加边界层来加密，但是在直角处生成的边界层网格看着不是均匀的正六面体网格

虽然checkMesh显示的网格质量还OK，但是有没有进一步提高的方法

@studentTan nCellsBetweenLevels 过渡层设置多一点，试下10层或20层

nCellsBetweenLevels		1;
