+ | ==== Results | ||
+ | The videos below compare the flow with different friction and yield stress values. In the first video, concrete has yield stress equal to 40 [Pa] and plastic viscosity 40 [Pa.s], while the friction parameters are 10.0 and 80.0. In the second video, the friction parameter is in both cases equal to 20.0 and plastic viscosity to 40 [Pa.s], while yield stress is 40 [Pa] and 400 [Pa]. | ||
