Hi Paul Sorry if I misunderstood your question, but if you are reviewing results per ply (Sub Scope By: Ply) or by layer (Sub Scope By: Layer), leave results to show top/bottom (Position: Top/Bottom). In this way, for a given element, the actual results for top and bottom per element will be shown, which is what you want. ("Position" is referencing position of element, not position of ply/layer for the situation you have.)
The reason why we have this setting is because, if you had an element with a definition of more than 1 layer, you may wish to see what is occurring at the topmost or bottommost part of a given layer (ply), so a user may wish to change it to the non-default option of "Position: Top/Bottom". However, in your case, you just want to use the default setting of "Position: Top/Bottom".
Think of the "Position" as being an option per element for your case - do you want only the top, only the bottom, or both top & bottom results shown on a given element? To see this more clearly, change "Display Option: Averaged" to "Unaveraged". If you review results with "Position: Top/Bottom", you will see gradient through the thickness direction. On the other hand if you use "Position: Top", the result should be uniform through an element's thickness since you are only showing results for top of the element(s).
BTW, it may be easier for you to just use "Sub Scope By: Layer" and review all results for each element at once. You can then use ply-based results if you want to focus on results of a given ply.
