Visualize overset mesh movement
Hello, I am trying to simulate a wind turbine using overset mesh and DFBI mode. I want to visualize and record the movement of the turbine during the simulation. ¿How can I do that?

Create a scene of the thing you would like to see. In the scene properties go to attributes>update and check the save to file option. Configure there how often you would like it to save, and run the simulation.
|
Also, if this is a wind turbine, why do you need overset for that? You can just use RBM.
|
Because I want the wind velocity as an input.
Is there any way to calculate the inertia values for DFBI? Thx. |

To find the moment of inertia you need to know the mass distribution of the object, I don't think STAR-CCM+ can calculate it. |
You are right, I thought RBM had the rpm as an input. Thx a lot.
I have simulated the same geometry changing some parameters: wind velocity, inicial inertia values (I don't know what this means) and DFBI object mass. None of them change the rpm obtained. Do you know what I am doing wrong? |
Make sure the region that rotates has its motion set to 'DFBI rotation and translation' and only enable rotating in 1 direction.
If you don't know what the inertia values are, you need to take a step back and read about some basic rotational kinematics, you shouldn't be doing this problem yet. https://en.wikipedia.org/wiki/Moment_of_inertia |

Yes, I don't remember what I did wrong but it works now.
