Results changing for same model after copy and paste

  I am simulating a parabolic reflector fed with SWA. For this simulation I am using the IE boundary for the reflector and the FEBI boundary for the source/feed. To get the required results, I varied the F/D ratio. I copied and pasted the model. Now when I simulate it, I get different results. I have three models, which give three different results. Or I can say I get the same result for different FbyD values in three different models.
  
  Could anyone help me understand why this is happening and how I can rectify it?

  When simulating models where the shape of curved surfaces affects characteristics, such as reflectors, right-click while selecting the curved surface object and set Assign Mesh Operation > Apply Curvilinear Meshing.
  Also, consider reducing the Maximum Delta S in Solution Setup.

  I have applied curvilinear meshing. And using max delta 0.02 with 6 passes.
