Hello everyone,
I'm modeling on ansys apdl.
I would connect two different elements: beam 188 and shell 181 with cerig command.
I tried to apply cerig command with this code:

"
allsel,all,all
!Cerig beam e shell
csys,12 !12 is the local system for the beam

! MASTER node
NodoMaster=node(0,0,0)

! slaves
csys,global !shell is defined in the global system
alls
nsel,s,loc,y,1740,1750

cerig,NodoMaster,all,all
allsel,all,all "

Sadly it does not work, error message is "the independent node (node number) is undefined or unselected. The cerig command is ignored"

Has someone idea about any solution for this problem?

Hope you can help me, thank you very much
