Web6 sep. 2010 · It is defined as the scalar product of the power flow and the normal vector to the boundary. However, I am totally confused about the definition of the normal vector of a plane boundary in COMSOL. For example , an plane x=-0.1, the normal vector should be [1 0 0],right? The normal vector of boundary 1 is [1 0 0] or [-1 0 0], why the outflow ... WebBecause when we think about a normal vector to a surface there are actually two normal vectors. There-- based on the way I've drawn it right over here, there could be the one that might pop outward, like this. Or there might be the one that pops inward, just like that. Both of those would be normal to the surface right there. ts co. ltd

WebTherefore, the unit normal vector at P can be used to approximate N(x,y,z) across the entire piece Sij, because the normal vector to a plane does not change as we move across the plane. The component of the vector ρv. at P in the direction of N is ρv·N. at P. Since Sij. is small, the dot product ρv·N. changes very little as we vary across Sij, WebThe vector is called the curvature vector, and measures the rate of change of the tangent along the curve.
