I assume the case was Fluent case 2D axis-symmetric case. CFD-Post cannot handle "true" 2D cases for that reason it made a pseudo 2D by creating a pie sector for axis symmetric (and use then periodic) or use symmetry planes for 2D planar after extruding it with one cell depth in the in-screen direction. You can post-process on these periodic "planes".
