Hello Jesus,
There is not a way to output "nodal vel" for an AMMG, if that is what you are asking.Â
I do not understand your ultimate and precise objective. If you can describe that in details, maybe I can suggest an approach(?).
By definition, an AMMG or ALE mat/part flows through an ALE computational domain. The nodes are eulerian nodes (fixed ref. frame). As the ALE mat passes through a node, its vel is record at that node as an instantaneous vel. As the AMMG passes by and away from that node, it no longer belong to the AMMG. For LAG part it is very easy to follow the mat because the node is fixed to the mat. For ALE/Eulerian mat, the concept is different. We may not be able to always have the node collection that belongs to an AMMG. So we cannot output that nodeset's nodal vel at every time step.
