Symmetry in a 4 point bending test

  Hello,
  
  I am simulating four-point bending test for glass specimens. I am making use of the symmetry and only modelling quarter plate. I want to know if I should apply symmetry only for the test specimen or for both the specimens as well as the support and the loading rollers. I have attached the pictures for both cases. I am using Ansys student v19.0.

  All parts/faces on the symmetry plane should have a symmetry BC.
  
  Also do not forget the z - symmetry at the YX plane at the point of maximum bending moment (middle of the plate).
