Is it possible to follow the position of the center of gravity of a liquid with HyperMesh

Victor_21202

Hello everyone,

I am working on the movement of a fuel tank half filled. The fuel tank is pushed by an actuator which implies a movement of the fuel inside. I would like to extract the center of gravity of the fuel during this movement but I do not know how to do it. I did not find output blocks in HyperMesh that were able to extract it.

Does someone know how to do it?                                                                                                                                                    Any help would be greatly appreciated. 

Thanks

Hi

I understand you are using Radioss as the solver of your model.

Not having much information how you modeled the fluid, you can request as  time history output with /TH/PART  the center of gravity coordinates of the part.

You can find more details of this card in the documentation.

Hope this is helpful.
