Minimum Averaging
Minimum averaging extracts the minimum values from the surrounding elements attached to a node.
For example, as shown in the Nodal Averaging of Elemental Results topic, there are four tensors, [A2], [B1], [C3], and [D4] at four corners at Node 400.
Element Type  Reference System  Projection Rule  Description 

Solid  Global  N/A  All corresponding tensors and vectors are transformed to the global coordinate system and then a component or invariant is averaged as explained above. 
Analysis  N/A  All corresponding tensors and vectors are left in their original coordinate system (no transformation occurs) and then a component or invariant is averaged as explained above. In this case, each participating element result can be in a different system. Minimum averaging for components ignores variations in systems. Since invariance does not depend on the coordinate system, all reference systems will produce the same results for invariants.  
Elemental  N/A  All corresponding tensors and vectors are transformed to the elemental coordinate system and then a component or invariant is averaged as explained above. In this case, each participating element result can also be in a different system. Minimum averaging for components ignores variations in systems. Since invariance does not depend on the coordinate system, all reference systems will produce the same results for invariants.  
Userdefined  N/A  All corresponding tensors and vectors are transformed to the userdefined coordinate system and then a component or invariant is averaged as explained above.  
Shell  Global  ON  All corresponding tensors and vectors are transformed to the projected system
(following the projection rule) of the participating elements and then the
component or invariants are averaged as explained above. As a result, even if the reference system is the same, the projected systems in participating elements can be different. Minimum averaging for components ignores variations in systems. 
OFF  All corresponding tensors and vectors are transformed to the global coordinate system and a component or invariant is then averaged as explained above.
