 March 28, 2009, 23:34 #4 New Member   anonymous Join Date: Mar 2009 Posts: 3 Rep Power: 10 Relate to moment coeffcient, we must choose correct reference values. I am using 2D model. Could anybody tell me how to choose correct these values? So, in 2D problem, unit of these quantities are such as M [N], [kg/m], v [m/s], A [m], L [m], correct? For example: a rectangular with dimension WxH = 0.3 x 0.1m, rolling on calm water surface level 1.5m. What I should choose reference values for v, L, A...?
