The system furthermore has fixed degrees of freedom in the form of ‘pins.’ The size ratio of pins : small particle : large particle is 0.004:1:1.4. Pins are located on a square lattice. We study the microscopic and macroscopic properties of our system with and without pins in response to shearing. We show preliminary results for pressure and shear stress as function of shear rate and packing fraction. We show velocity and local shear stress profiles. Microscopically, we find that pins impede the propagation of velocity and shear stress far from the walls.Furthermore we study the time evolution of D2min and its relation to the contact number.
