You don't double the stress on a half symmetry model.


If you applied a force to a face that was cut in half by symmetry, then you would apply half the full model force because the other half of the force is on the missing half of the geometry.


If you applied a non-zero displacement to a face that was cut in half by symmetry, you don't apply half the displacement, but when you request Reaction Force, you double that to find the full model Reaction Force because the other half of the force is coming from the missing half.
