Dear FOAMers,
Hello everyone. I am currently trying to simulate flow around a VAWT using pimpleDyMFoam. But my solver is not working properly. It is crashing repeatedly. I have used different types of meshing and boundary conditions. But nothing seems to work. After a few time steps pimpleDyMFoam is crashing. Right now I am in a kind of frustrating situation. Here are my case files: https://dl.dropboxusercontent.com/u/...ne/Turbine.rar I would appreciate any kind of help. |

Dear Naruto
I also simulate straight Darius type VAWT using AMI. I think you might have to be check your mesh quality using checkMesh command. I suspect that meshes of high aspect ratio and high skewness would be found. Sincerely waku2005 |

Thank you for your kind and informative reply. I was a fool to post this thread. Yes you are absolutely right. Just after posting this thread, I checked my mesh using CheckMesh command and I found high skewness and non -orthogonality. I did not check this mesh before because I was quiet sure about the quality of the meshing. I would rebuild the mesh and than try simulation again. I will keep updating this thread.
