Reply To: How to apply displacement derivative dependent force on bunch of nodes in apdl?

[Mehdi Baghaee]

The load formulation (P=dW(x,y,z,t)/dx+dW(x,y,z,t)/dt), is a well know aerodynamic piston theory used for modeling supersonic air flows on plates (panel flutter).

Let me know if anybody could help to model it through ANSYS APDL.🙏
