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.

Subject: [Nektar-users] Question about the flow stability computation of a moving 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!
