Well, after many days and countless hours I have gotten Cl and Cm to behave.
I did it by changing the refinement procedure I used to create the base mesh which only gets its x,y,z Background Mesh Box cells changed to create all the other meshes in the study.
At some point when I have some time I will post back here what my refinement procedure actually was that allowed me to obtain a minimum value of % inflated for ALL meshes in the study of 98.6%. (EDIT; Actually it needed to be described anyway to carry on, here it is, a few posts ahead of here)
All study meshes have square cells (exactly) on all faces of the Background Mesh Box.
Again, I am using vertical scales on all plots that represent the plots data parameter as a percentage with respect to the value of that same parameter, in the mesh with the highest # of volumes (this highest volume mesh is expected to give the most accurate results). This eases the mental burden of just looking at numbers and trying to figure which is better and by what percentage.
Here is the study:
Unfortunately, though Cl and Cm are behaving, pressure drag is not.
EDIT; Since I did this study I have come to realize that I should not look at Cm as a variable that should be evaluated as a percentage of the previous iteration for MIS study use. The reason is that we can re-map the Cm to any value, including 0, simply by moving the Reference Center if Rotation point that determines the Cm moment arm for any simulation run. So, please ignore the Cm plots…
