Cylindrical coordinate system.I'm applying the acceleration DOMEGA as a stepped load in the transient analysis. Result Code:WSE0000100000-RH8W0M. In ANSYS, for Fixed support, we restrict all the DOF at a point, edge or face. I have activated large deflection and Uniform Reduce Integration using following commands. Boundary condition is fixed support on to ends and internal pressure of 10 (Pa) which have been implemented to increase gradually from 0 to 10 (Pa) in 30 steps. Geometry is a cylindrical tube with external radius of 4 mm and thickness of 0.47 mm.

Although this command is very much valid for transient analysis (for example, as a constant throughout loading), using this command in the way you have described is meaningless, and I would reconsider your strategy. What you should see here are stresses in the disk due to centripetal forces. This command issued within a static analysis (ANTYPE,0) will give you what you need. You will not see the model rotating because that is not the nature of the usage of this command.
