AMI: Patch Error
1 Attachment(s)
hi everyone
I tried simulating a compressor fan using rhoPimpleDyMFoam solver with cyclicAMI similar to the propeller case in tutorials compressor model was taken from grabCAD and meshed using snappyHexMesh. My simulation stops after few iterations showing this Code:
solidBodyMotionFunctions::rotatingMotion::transformation(): Time = 0.00456585764 transformation: ((0 0 0) (0.9999348537 (0 0.01141439623 0))) Code:
Create time Thanks |
Can someone please help me with this , I'm stuck with this error for days.
|
So this error appears after a few iterations? Maybe the axis of rotation is not correct, so that the cells are not rotated correctly?

Thanks for your reply For my rotation : origin (0 0 0) and Axis is (0 1 0 ). Please check the pictures attached and let me know if there are any changes in these parameters. |
Origin and axis seem to be okay.
Where are your cyclicAMI interfaces? After the trailing edge of the compressor wheel? |

Yes
I have enclosed the compressor with a cylinder. check the pictures attached. Let me know if you need anything else to check what the problem is. |
Do you have access to Anysys products? Fluent, Gambit etc??
|
I have access to Ansys ICEM CFD.
|
The error may be due to the fact that your 'rotor' and 'rotor-slave' do not match at the interface/cyclic-AMI. I usually use Ansys-Meshing to avoid this error and for better matching of boundaries at the interface.

@vasava
Thanks for your reply , i figured it out that it was my meshing problem but checkMesh says everything OK. Anyways il try out Ansys icem for meshing. |
