We present a first-principles theory for plug-free dense granular flow. This\nis done by coarse-graining directly the microscopic dynamics and deriving an\nexplicit relation between the macroscopic stress and strain rate tensors. The\nnewly derived relation not only differs significantly from that of the existing\nempirical models for such flows but it also provides a novel understanding of\nthe effect of rigid-like rotational regions in the flow.\n
