Impeller simulation with fluid-structure interaction and deformed mesh

i try to simulate different impeller geometrys and analyse the different resulting fluid velocities.
Therefor i started based on this comsol blog entry:
www.comsol.com/blogs/deformed-mesh-interfaces-rotations-and-linear-translations/
After that i added a Fluid-structure interaction physic node, but i keep getting the error-message:
"Failed to find consistent initial values.
Segregated Step 1
Undefidned variable.
Variable:comp1.fsi.K stress tensor testXY, Geometry: geom1, Boundaries:3,4,6,7
[..]"
But i don't know what to add or what boundary condition is wrongly applied.
This blog entry:
www.comsol.com/blogs/how-to-improve-your-paddle-stroke-with-simulation/
It shows almost what i want to figure out. But i just need the rotating "paddle"
Could you have a look?
thank you and kind regards
Jan

I have the same problem with you.
Have you found the method to simulate the rotating structure object in fluid with Fluid-Structure interaction in 2D or 3D model?
And your suggestions are highly appreciated!
Best wishes,
