1.Multiple /XREF entries are allowed in RADIOSS input, even with different reference coordinates for the same nodes belonging to different parts. Reference metric will be applied to shell and solid elements only. The list does not need to contain all nodes of a part. If no coordinates are given for a node, initial coordinates are used instead. Also, if nodes not belonging to the specified part are listed, they will be ignored.
2.Reference state is available:
•for shells using law /MAT/LAW19 or /MAT/LAW58
•for 4-node tetrahedron elements and 8-node bricks using Isolid =1, 2 or 24 and Iframe =2 (co-rotational formulation) and material laws /MAT/LAW35, /MAT/LAW38, /MAT/LAW42 or /MAT/LAW70
