problem 1
Frist, we should set boundary condition(after-wards b.c). There are four homogeneous b.c and three non-homogeneous b.c in this problem. It is important how to deal with these three non-homogeneous b.c. To deal with this issue, consider the fact that linear system can be broken up into two parts: the equations that correspond to the known displace parts with unknown force, and the equations that correspond to the unknown displacement parts with known force.

problem 2
In order to use symmetry in the shape, a step file symmetrical to the center of the circle was generated, and then a mesh was produced using the gmsh program.
The left picture below is the process of creating a step file using free-cad, and the right picture is the process of creating a mesh using gmsh.

The element size was adjusted to match the number of nodes to 25, 50, 75, 100, 120, and more for cst elements and quad elements.
