Hey Rob!
I got you, but I consider that the velocity scale in the image I showed you, it is not relevant. Instead, I find odd the sudden changes of the velocity contour in so few time steps.
The results of the fixed mesh and the movement of the fluid around the ellipse looks sensible to me as well and confirm that the mesh can be suitable for the analysis.
As for the contours, when I use Overset meshes I always verify that there are no orphan or dead cells. I attach as an example this image:
Rob, In the post-processing, the contours generated by FLUENT usually show discontinuity in the areas where the "Overset interface" is located. However, it seems to me that it is only a graphical inconsistency of FLUENT because in other cases using CFD-POST that doesn't happen. Has it happened to you too?
