To make a structured mesh in gmsh, shapes with four sides are needed. At this point, the circular shape can be meshed with a structured algorithm, but the region outside of the circle can't. This region is next broken into four sided shapes as shown in the input below. // break area outside circle into four surfaces.

Pygmsh example. I talked with him and he was not very interested in how to use pygmsh properly-the only condition is to use pygmsh. I am new in all this so its hard to just find solution. But to have meaningfull code I decided to create my own geometry with data given to me. On this example I am not able to create quad mesh on the cube surface.
