How can I get a centerline of a cylinder to be fixed?

Hello everyone,

This is a solid cylinder. I want to use Structural ANSYS Workbench to analysis thermal deformation. Can I fix the centerline of the cylinder but the thermal deformation can be done in the radial direction? That means the centerline of this cylinder is not changed but this cylinder can expand in the radial direction ( and also the torque can be done about x axial).

    Hi @ToanNguyen ,

    You can try applying displcement x=0 at one face and then apply the thermal condition. Also, turn on the weak springs to avoid pivot errors. With this you will see the cylinder expanding in radial direction.
