Hi Li-Ming, I have a local Nektar++ version able to do linear stability analysis only for the rigid body and for translation. You can access this version on GitHub https://github.com/Ig-dolci/Nekta--sens-stab. Any questions, please let me know. Best, Dolci.

Hi Liming,
As far as I know, there are two methods to simulate the moving body, 1, use time-dependent mapping of coordinates; 2, add a MovingReferenceFrame body force and solve the absolute velocity in the body frame, examples are given in the latest master branch solvers/IncNavierStokesSolver/Tests/ Moving_reference_frame_Rot.xml, Moving_reference_frame.xml. Method 2 only works for a rigid body.

Dear all,
Sorry for my interruption.
I want to use Netkar++ to investigate the flow stability around a flapping plate. However, I found there are no tutorials about the moving body. Would someone kindly give me some suggestions or share your tutorials about the moving body?
With best wishes!
