meshing - mesh is generated on cylinderical shape and NOT the actual part (cylinder)

I am sorry I forgot to enclose the FreeCAD file - here it is

[askmesh123]

All - I finally solved this secondary (yellow) meshed square long block.

This meshed yellow thing shows up If I do not click "Write mesh case" and directly if I go to "Run mesher" then if you to "load surface mesh" you will what I saw this yellow meshed thing and the part remain "unmeshed". Then if you see in Paraview it just shows that yellow meshed thing - dummy- there.

The procedure is to first save "Write mesh case", next "Run mesher" then "load surface mesh" - then "Paraview"

An elementary mistake.

Thank you all..
