I have a cylinder with shell mesh. on its axis I have a beam with the same length of the cylinder. I want to create an RBE2 between each end edge nodes of the cylinder and the corresponding end node of the beam. how is this possible using APDL ?

Assuming top_beam_n is a component with the upper end node of the beam, top_cyl_n is a component with the upper end nodes of the cylinder, you can do:
cmsel,s,top_beam_n,node
*get,num_top_beam,node,all,num,min
cmsel,s,top_cyl_n,node
cerig,num_top_beam,all,all

$\begingroup$ Thanks a lot ! but I would also like to know how to collect the end nodes in top_cyl_n and maybe also the beam $\endgroup$ Commented Aug 28, 2019 at 9:39

$\begingroup$ You could select nodes by location with a
nsel,s,loc,z,0incsys,4with your workplane located at the top of the beam. $\endgroup$– ÖskåCommented Aug 28, 2019 at 11:30 -
$\begingroup$ Thank you so much ! when I get the locations this way, will they also be put in the set named "S" already ? $\endgroup$ Commented Aug 28, 2019 at 11:31

1$\begingroup$ You should check the help for the
nselcommand. Thesin that case stands for "Select" and means that you select every nodes where the workplace is located. If you want to separate the nodes attached the areas/lines, you can do something likeesll,sand thennsle,sfor lines, andesla,sand thennsle,sfor areas. $\endgroup$– ÖskåCommented Aug 28, 2019 at 11:36
