AMI with linear translation motion
 
2 Attachment(s)
Hello everybody,

I'm trying to simulate a linear translation motion of a solid body with OpenFOAM 2.1.0, in a turbulent flow (in 3D). I would like to use the AMI tool, to avoid the constraint of the mesh deformation while the body's motion. But I have a problem: it seems that there aren't interpolations between the two AMI that I use, and it produces strong errors at the interface, on all fields (p, U, k...). Do you know if this utilisation of the AMI could work? And if not, do you have any suggestion to manage to solve my problem?

Thank you!!


PS: I have attached two pictures, the first one is a 2D view of the mesh (the solid body which has to move to the top of the duct is situated at the right of the obstacle), the inlet flow is at the left; the second one is a view of the non-interpolation problem...

Hi,

did you solved your problem ?

I would like to compute same kind of flow.

Best regards,

Stephane.
