For such a thin model the elements at the centerline are going to be poorly shaped.  Also, in a 3D model, an edge is a singularity.  It has no cross-sectional area so the stresses go to infinity.   In a 3D model the fixed edge cannot resist rotation so a tangential constraint should be specified somewhere in the model.  It would be better modeling practice to create a small axial hole at the center of the model and fix the face of the hole.  That would address all three issues.
