Hello! I am new to ANSYS Fluent and i am trying to simulate a 2D floating body in water when wind is blown through it. I restricted the motion to 1 DOF rotation and simulated the setup for some seconds.
I assumed that the motion history would give me the angle of rotation of the body when wind hits it but now i am thinking that might not be the case. flat.png rotated.png Ive attached pictures of the module at the start of the simulation and after 9s. The orientation angle after 9s is shown as 63 degrees which is strange since the module movement does not reflect this. I hope you can see this as well from the pictures startorient.png endorient.png What am i missing here? What exactly does the motion history measure? It would be really helpful if someone knows whats going wrong here and can suggest any alternatives that would give me more accurate results of the body rotation! |
