How can I select nodes in a cylinder?
How can I select nodes in a cylinder?
(OP)
Hello,
I'm a beginner in Ansys and I have made the model of a piezoscanner, but at the moment I'm not able to select the exterior nodes of my tube!
!Geometriparameter des Piezo
OD = 6.35e-3 !Außendurchmesser (m)
ID = 5.35e-3 !Innendurchmesser (m)
L = 10e-3 !30e-3 !Länge
ET,1,SOLID5,3 ! 3-D COUPLED-FIELD
...
MAT,1
TYPE,1
CYL4,0,0,ID/2,0,ID/3+OD/6,0,L
CYL4,0,0,ID/3+OD/6,0,ID/6+OD/3,0,L
CYL4,0,0,ID/6+OD/3,0,OD/2,0,L
VGLUE,ALL
Regards

RE: How can I select nodes in a cylinder?
just define a cylindrical coordinate system and then select the nodes at the distance of the exterior area:
CODE
nsel,s,loc,x,od ! note that in cylindrical coordinate x is the radius

Thank you for your help!

RE: How can I select nodes in a cylinder?
With the command:'nsel,s,ext' I got the nodes inside th hole of my tube,too!
Another question: I want to select only the nodes in a specific angle.
I tried this command: 'nsel,r,ang,xy,?,?', with degrees, with pi and so on, but I only get 0nodes or all nodes I already had!

RE: How can I select nodes in a cylinder?
to select the nodes in a specific angle you use also the keyword 'loc':
CODE
Here is the y coordinate the angle, since the coordinate are cylindrical. Asys uses the same notations (x,y,z) for each coordinate regardless of the used coordinate system.
