Apply Rotation in a Structural-Thermal Ananlysis

[modeltech]

Hello all,

I am creating a transient simulation of a rotating pipe that will have a heat flux applied to its inner surface. I figured out how to do the heat flux but I can't figure out how to apply rotation to the pipe. I tried using SOLID226 (because it is a coupled field element) and created a cylinder extruded along the x-axis, meshed it, and then used:

OMEGA,10,,,,

to apply the rotational velocity about the x-axis. The result was the pipe moving in the negative y-direction.

Any help or a link to an example is greatly appreciated.

Hi

I also had problems with this but after some trial and error. The best way of doing this is using a Joint load--> Accelleration. So you need to define a Revolute joint to ground at the center of the tube.
