Multiple AMI zones not working

Hello everyone!
I'm trying to study how the wake produced by a wind turbine affects to another wind turbine placed next to the first one (Check attached images for a visual). For that purpose, I set a 2D case with 2 vertical axys wind turbines with 1DoF each and two AMI zones, so I can get a flow induced movement. (I'm using this Holzmann tutorial as a base case: https://holzmann-cfd.com/community/t...l-wind-turbine). Also, I'm using OpenFOAM2012, as long as OpenFOAM8 doesn't support multiple 6DoF body motion. Everything works fine when I give 1DoF to only one turbine (doesn't matter which one) and the other stays as a wall, but when I try to give 1DoF to both of them, the solver crashes after a few iterations. After checking the logSolve file and the mesh in paraview, it seens that the second AMI zone destroys the mesh (see detailed images). Here is a extract of the logSolve file, where you can see how Patch target sum weights (Red line) it is not close to 1 anymore and in consecuence, p diverges and so time steps continuity error gets huge just before simulation crashes: Code:

Could someone please shed a light about this issue? I would be really grateful for any kind of suggestion, I've been weeks stuck on this. If you need any more info, please ask for it, I'm quite new to OpenFOAM and I don't know if I have explained myself correctly. Thank you for reading. Pedro. |

Hi,
Does the Courant number increase during the steps before the crash? If the courant number increases above 1, the simulation will crash. Would it be an idea to create a refinement area between the interacting wind mills? |

Hello abeda, thanks for your reply.
Courant number is limited to 0.8, as you can see in my controlDict file. I have tried lowering Co to 0.3, but it was useless. Maybe I can try a finer mesh, but I won't be able to make a new mesh until next week. Best regards. |

Hi,
I didn't mean the courant number given in controlDict file. Sorry for being so unclear. I believe pimpleFoam also prints out the courant number between each time step. So, what is the courant numbers printed out by pimpleFoam right before the crash message given below? When you reduced the courant number in controlDict file to 0.3, did it crash sooner than when the courant number was 0.8? Error message: Code:

Hello abeda, sorry for the late reply.
Here is what I get when I use maxCo = 0.8 (this is the last piece of info about Co, since in the next iteration the simulation crashes): Courant Number mean: 0.0197082 max: 0.831334 deltaT = 3.81029e-05 Time = 0.000922992 And here MaxCo = 0.3 : Courant Number mean: 0.00579354 max: 0.332099 deltaT = 1.05022e-05 Time = 0.000232002 Looks like in both cases the simulation crashed when maxCo is surpassed. Also, I have notice that both of them crashed at the same iteration (PIMPLE: iteration 4) even thought time step is smaller where maxCo = 0.3 Thank you for replying and sorry again for my late reply. Best regards. |

Please, does anyone have any experience using multiple AMI zones? I am still stuck on this, any piece of advice would be really welcomed.
Thank you |
