I'm simulating thermal deformation by using Ansys Workbench (Structural module). There is a cylinder pipe as shown in Figure. The pipe can rotate around z-axis and the thermal deformation in radial direction only (That means the axis of the pipe is fixed and others are free. How can I apply these constraints?
Thank you so much.November 9, 2020 at 3:19 pmDragana JandricAnsys EmployeeYou can use remote displacement with the options to fix/free all translations and rotations. nNovember 10, 2020 at 1:54 amNguyen Van ToanSubscriberThank you for your reply. I tried that but I didn't obtain the results.nNovember 10, 2020 at 3:28 amBenjaminStarlingSubscriberif this is a structural analysis, or coupled thermal-structural, there is no way to apply this boundary condition. If rotations in Z are free-free, you will have solver pivot errors. You can possibly simplify your analysis into an axisymmetric analysis, dependant on your load also being axisymmetric. The other option is to utilise a free-fixed constraint in Z rotation. I would do this with a remote point, and on one end of the pipe, fix rotations in Z.nViewing 3 reply threads
