Question

After the calculation, an opening modeled circularly is displayed as a rectangle.
How can I fix this problem?

Answer

The consideration of curved elements depends on the FE mesh refinement.
An FE element always has straight outer edges.
If you select too rough FE mesh, the result is a very inaccurate display of the curved elements with the straight lines.
If the global setting of the target length of the finite elements is specified with the sufficient accuracy under "Calculation" → "FE Mesh Settings," you can also specify a local FE mesh refinement on the nodes, lines, or surfaces.
