what command should i use?

[volaff]

Hello everyone, it's been a while since I've been writing in this section and I hope I'm not rusty.

for educational reasons, I would have the need to go to couple two parts so that, in fact, I form a whole.

I was wondering what kind of command would I/dpvre use to do this?

In practice I have a loaded plate and another one that is attached to this.

it would be convenient that each node of the loaded plate was tied to the node of the plate that should stand attached above.

I would like the software to consider the two plates as a whole: that is when a plate is pulled the other las follows because it is attached to it.

should I use contacts necessarily!?

if yes, what kind of command? What, cp, or anything?
I heard about it, but never used it.

As in everything, perhaps there are more opportunities to operate, I would need a simple but effective solution, and perhaps here I ask too much

thanks to everyone for the attention.

If you need to make a mechanical contact, you need to use surface elements on contact surfaces

thank you very much for the answer but I should try to solve the problem as simple as possible avoiding the use of contact elements.

I had thought of the cp command making a rigid link between the two first and working on coincidence knots.

Thank you for your interest!

Good Sunday

you already have the answer do not ask

for those who had the same problem here is the solution grateful to eih64:

/prep7



cm,nodes,node


!nsel,r,p!!select all coining knots (in cup of two)


*get,numb,node,count!!memorise in numb the number of nodes
*do,i,1,numb/2,1!

*get,n1,node,,num,min!! memorizes in n1 the smallest node number

n2=nnear(n1)!! stores in n2 the number of the node closest to n1 (in this case the coincidence)

e,n1,n2!! creates element between n1 and n2

No!

No!

*end
