I am trying to do flutter analysis in ANSYS workbench with 2 way system coupling. However, there is a point am concerning. The problem is that, with the Transient structural module of ANSYS I will transfer only bending (flexural) data to the Fluent but flutter needs torsional deflection at the same time. How can I design my project? Thanks from now for your advices.
Regards
better go for aero elastic analysis in NASTRAN it is the easy way to find out flutter analysis.
you can find in aeroelastic analysis in NASTRAN FOR FLUTTER ANALYSIS.
I think you can so many answers and explanation of your problem in e media. just google it
There is a simple way of dealing with that:
Instead of modelling the full body, compute the equivalent bending and torsional stiffness at the desired point (even if your cross-section is complex, you should be able to get the torsional stiffness from Poisson equation);
After that, model the section as a rigid body in FLUENT or CFX (you won't need a 2-way coupling that way) and input the rigid body parameters.
I did that for a cylinder using CFX and the results are great! If you want, I can send you the workbench project so you can take up on the main ideas.
