CONSTRAIN IN CYLINDRICAL COORDINATES
CONSTRAIN IN CYLINDRICAL COORDINATES
(OP)
All,
I have this weld section of a large cylindrical structure I need to analyze. I have used cylindrical coordinates to account for thermal expansion. However, I need to constrain the model in the radial direction to prevent rigid body motion and at the same time, I must allow radial expansion in the X direction. Currently the body is constrained in the Y and Z directions of the cylindrical coordinate system.
Thank you!

You can use Frictionless Support on the faces of the cut section and zero displacement on the bottom/top face, UY in your case. This should allow radial expansion due the temperature.
