Thanks Rob, I was not looking to do either of those things. I went back and evaluated the manner that I created the interfaces between the sliding mesh and the stationary region. I rebuilt some of the model and am attempting to complete the DPM iterations once more. They appear to be taking a bit, but I am no longer recieving the same error. So indeed it was something to do with the interfaces, but I think it was more so my definition and creation of them.
I will update if my modifications work, thanks for the insight as always!
