Select nodes fron center line

[eraserwww]

Hi,

I have written a simple python program which will help me select a center line of nodes in a square unit cell with the fiber in the center ? Too I have change de system of coordinates of a edge nodes, I created a system cylindrical, selected the nodes and sets but a don't obtain how change them of the retangular to cylindrical ?

Hi,

I have written a python program to determine the properties in the unit cell with square arrangement and circular cross section. I have applied BCs in the edges lines iun the cell. I set this edges and nodes from line, then I must be changed the nodes for the cylindrical coordinate and have their angular displacentment constrained in order to avoid rigidy body.

a.Set(edges = a.instances['Square-1'].edges.findAt(((-side,-side,side),),), name='Edge-')
a.Set(name = 'Nodes-', nodes = a.sets['Edge-'].nodes)

Can I helped me to select all nodes from center line perpendicular to X-Y plane have X and Y displacements set to zero ?

Thank you for your insight.

Pictures would go a long way. I believe that you need to split your model to on this center line to create the geometry that you want to constrain. I hope this helps.
