[Gmsh] Uniform mesh on L-shape domain which contains a arc of circle

[mohamed mbehou]

Dear,
I am a PhD student at the University of Pretoria and working on finite element, and I am a new user of GMSH.
Please how can I get the uniform mesh on the domain (Plan Surface(13)) and the refine one in the arc of circle (Plan Surface(15)). The domain is defined below. I tried the transfinite, it can't work.
Your help will be very useful for me.
