Hi

At first, you must create a bounding box to choose nodes:

1) Get the nodes list using

allNodes = mdb.models['Model-1'].rootAssembly.nodes

If you choose a dependent instance, Get the nodes list using

allNodes = mdb.models['Model-1'].parts['Part-1'].nodes

2) create a bounding box

delta = 1.0e-5

xmin, ymin, zmin = x-delta, y-delta, z-delta

xmax, ymax, zmax = x+delta, y+delta, z+delta

3) Get nodes that lie inside the bounding box

myNodes=[]

myNodes = allNodes.getByBoundingBox(xmin, ymin, zmin, xmax, ymax, zmax)

So, now you select the specific node in your specific coordinate. You can do it for all nodes with creating a loop.

At last, using this code

myNodes[number].lable

Hi @Meysam Ghorbanpoor. Please accept my sincere thanks. Your answer was Intelligent. In completing your answer, I must use the Cylindrical coordinate system in step 2 to find x, y, and z according to the radius and elevation position.

Hi

I'm glad to help. Yes, you're right, in your case, you must use a cylindrical coordinate to choose the nodes.
