sorry the continuous questions today! I am going to use symmetry for the geometry as in the picture I attached. The simplified geometry is a multilayer (only the green part) composed of layers of different materials and thickness, and four strips A (=C) and B (=D) jointed on top and at the bottom of it.
For time calculation reducing (I have to deal with a more complex structure), I would use symmetry, as A=C and B=D, with a plane of symmetry in the middle of the multilayer. Therefore, I would consider only A and B in the calculation, for example.
But I can't use Symmetry, as it is required a face in the middle plane of the multilayer, but the multilayer is not Symmetric! I should need something like a plane recognized by the function Symmetry, and not a physical surface.
Thank you in advance
