loop over the node component/selected node, in which nodes numbers are not in sequence. 2

Hello, everybody

Is it possible to loop over the node component or the selected node numbers, in which nodes number are not in sequence.

Thank you a lot

Use the NXTH function from *GET. Your script may look something like:

nsel,s,node,,.......             ! select the node set
*get,currn,node,0,num,min        ! get minimum node num in variable currn
*get,num_of_nodes,node,0,count   ! get num of nodes

! Create a loop to carry out some function such 
! as finding the nodal x co-ordinate

*do,J,1,num_of_nodes
         ncx = nx(currn)      
	*get,currn,node,currn,nxth   ! Get the node number in the set higher than currn
	node = currn
*enddo

You can also use currn = ndnext(currn) instead of the *get,currn,node,currn,nxth

*get,nmax,node,platei,count
*get,minno,node,platei,num,min

*dim,p1node,,nmax

n0=minno
p1node(1)=n0

*do,i,2,nmax
n0=ndnext(n0)
p1node(i)=n0
*enddo

*do,in,1,nmax ! start loop over all nodes in one plate
*get,xno,node,p1node(in),loc,x
*get,yno,node,p1node(in),loc,y
*get,zno,node,p1node(in),loc,z


dz = wopl*(b1*sin(pi*(xno-0)/a)+b3*sin(3*(xno-0)*pi/a))*sin(pi*(yno+375)/b)
n,p1node(in),xno,yno,zno+dz

*end do

Drej and Orel, Thank you two.

I combined what you two said, and write the above code, it works.

many thanks to you two.

cheers
