In a 3d project,the min y+ is zero,and the max is 500.As we all know,the suitable value for y+ is about 30,the mesh is structure,I can not change the min value into above 30 with the adapt method,what should I do?

you had better check out the velocities , if the velocity near the wall is great so for finding the proper values for y+ , you have to refine your mesh. and be sure the computing process has no problem.
