workbench画网格显示表面网格相交或接近相交，使得它很难创建一个体积网格。如何解决？

错误提示1.the surface mesh is intersecting or close to intersecting, making it difficult to create a volume mesh. please adjust the mesh size or adjust  the geometry to fix the problem.

2.a mesh could not be generated using the current meshing options and settings.
