Selection of node from a subset of nodes corresponding to maximum displacement in one direction?

01 January 2019 1 5K Report

How to select a node from a set of selected nodes and get the node number corresponding to maximum value of say y displacement. It should also take the mod (for selection of maximum negative value).

/POST1

PLNSOL,U,Y

*GET,UYNEG,PLNSOL,0,MIN

select the value of displacement whereas I want to select the node number corresponding to this displacement. Also it should be able to compare the max negative and positive values of displacement and give me the highest value.

Thanks for your suggestions Claudio Pedrazzi

. I used a combination of *SET,*GET,*MOPER,*DO,NDNEXT(),*MFUN APDL commands to get the node number corresponding to maximum displacement.
