Hello. I want to find a way
 

Hello.

I want to find a way to have a fine grid on both edges but a coarse grid in the middle. ( in x direction)
Since I want to have a similar grid resolution on both edges, the expansion ratio (deta_e/delta_s) would be 1.0.
Then I have uniform grid everywhere despite my intention of having a corse grid in the middle.

Regards,
Sungho
