Hi everyone,
The preprocessor Messages are:
open area mismatch at inter-block boundaries of all blocks
as % of total open area at these mesh boundaries = 2.98507E-01
How can I solve it?Thank you.

It means that the cell sizes between adjacent blocks are not optimal for resolving the geometry in the same way on either side of the mesh-block interface. Try to make the cells 2:1 across the boundary, and try to use cell sizes and mesh block extents in such a way that the grid lines match exactly between the two mesh blocks.
