Hello Foamer's

I'm interested in simulating a helicopter rotor.
I've done this with solidBodyMotion with AMI at the interface and works well

I would like to combine the two mesh solvers, dynamicMotionSolverFvMesh and solidBodyMotionFvMesh. Ideally, I want the rotating domain of the mesh to
use mesh elasticity on the rotor blade (located in the center of the rotating domain).

I tried using rotatingWallVelocity and just use dynamicMotionSolverFvMesh. Which does work, but the rotatingWall BC's doesn't work for blades (non circular surfaces)

It seems possible, but don't really know where to start. I assume many could benefit from the functionality.

Any suggestions as to where to start or any dev. versions which have incorporated this.

Hello EVBUCF:

I meet the same question as yours, and how did you solve this problem? Is there some suggestions?

Thank you!!!

If anyone have a solution for this problem, I'd be curious to know3 about it.
Thanks,

Hello everyone,

i read about this in the "openfoam technology primer" http://www.sourceflux.de/book/. Have a look at chapter 13.

Good speed.

can you send me your case file? thank u so much

Hi Carlos,

I have implemented exactly what you are searching for into mine fsi application. I wanted to simulate jet engine start up including the rotordynamics effects. Successfuly done it, but simulation time is enormously huge. So stopped for now.

If you are interested I can post the code.

Best regards,

Bojan

Hi, Bojan!
I am going on a similar case to yours, I want to simulation fsi of helicopter rotor, I have used solidBodyMotionFvMesh to simulation helicopter rotor in hover, now I also want to combine dynamicMotionSolverFvMesh and solidBodyMotionFvMesh to do a fsi based on OpenFOAM, can you send me your case files? my email is 1094351222@qq.com, thank you so much!

Hi, Bojan!

I am working in similar case like yours, I am trying to simulate a 6DOF sphere and I would like to combine dynamicMotionSolverFvMesh and solidBodyMotionFvMesh, can you send me your case files? My emai is marco.espinoza.autocad@gmail.com, Thank you!!

[Bojan]

Hi Marco,

I will send the code to you as soon as I reach home later today.

Best regards

Hi everyone!
I am also working to combine the two dynamic solvers. Bojan, it would be great to test your code, could you please send me it? my email is: extmgbox@gmail.com
Thanks in advance!!!
