[Gmsh] How to change mesh-size

[Tomohisa Simoyama]

Dear all gmsh user,

This is  Tomohisa Shimoyama from Hiroshima University, Japan.
I am new user of gmsh and nice to meet you.

I am trying tsunami simulation in Seto Inland Sea,Japan.
When I separate the region into mesh, I have a problem.
So far, coastal line is separated by fine and ocean area is separated by
rough.
However, I would like to define that Pacific ocean is more rough, Seto
Inland Sea is rough and coastal line is fine.
Eventually, I would like to make three pattern of mesh.
But, I only know how to make two pattern that coastal line is separated by
fine and ocean area is separated by rough.

Does someone know how to do it?
If you can, please let me know?

Best regards,

Tomohisa Shimoyama
