| Summary | 0004114: Issues with Newmark and Crank-Nicolson schemes for sixDoFRigidBody | ||||
| Description | The current implementations of Newmark and Crank-Nicolson schemes are incorrect. They are unstable due to errors in the implementation. | ||||
| Steps To Reproduce | The details of the issue and the case files for the zero fluid model are available at https://github.com/chennachaos/OpenFOAMsixDOFtest/tree/main | ||||
| Tags | No tags attached. | ||||

Can you provide a patch which updates the schemes how you would like them to be implemented for testing? |

Hi, I don't have a patch yet as there are some implementation difficulties. For implicit time integration schemes such as the Newmark scheme, we need to access the values of mass, stiffness, and damping, and because of the current design of the code, this does not seem to be straightforward. It would be good to discuss how this can be done properly. |
