apparent anomalies at ACMI interface

Hi,
I am investigating using the ACMI patch for a fairly simple 2D case as illustrated in the attached picture. The model is being solved using rhoPimpleDyMFoam and the solidBodyMotion FvMesh class. The translating mesh region (translating speed of 60 m/s) is 'empty', therefore one would expect mass fluxes across the ACMI face to be near-zero. However, I am getting quite significant values of velocity/density/temperature at the ACMI boundary. I have attached my fvSolution and fvSchemes and some results pictures to show this. Would anyone be able to suggest the cause of these apparent anomalies and how I might be able to get rid of them? On top of this, would someone be able to explain how the ACMI blending works in greater detail? Thanks |
