Can anyone help me, I want the effect of the target image! thx

Where does your reference image come from?
I’m guessing that what is shown there was actually a flat regular mesh with manually designed boundaries, then the vertices pulled to the boundary and the shape relaxed.

If you don’t manually design the boundary, and want a mesh with fully regular connectivity then it is harder, but here is one way. It uses a custom goal I made a while back adapted for this - snapping points to the boundary and relaxing. (71.8 KB)
