Morphing + superimposed motion

pi120 · June 14, 2021, 06:38

Hello,

I am modeling a floating wind turbine which has to translate back and forth (superimposed translation) but its blades also deform via fluid-structure interaction (morphing motion). As far as I know I can set up a superimposed translation or a morpher to a single region in star-ccm+.

Is it possible to apply a superimposed motion as well as a morphing motion to the same region in star-ccm?

Hello Pietro

It is possible. You should take a look at the avaliable tutorial under Solid Stress tutorial file in Help.
Tutorial name: FSI with Prescribed Solid Motion: Flapping Wing.

-The overset wall should be set to morphing with floating type so the overset region will compensate for the displacement of the object.
-You can then impose your desired motion.

I highly recommend you to take a look at the tutorial. It does an exceptional job explaining the details.

Take care
