WebThe characteristic length is the dimension that defines the length scale of a physical system. This implies that for any system, which my contain several length scales, there may only be one characteristic length scale. This is also generalizable to the other characteristic scales such as time, speed, etc. Webaverage diagonal dimension of the element (at least for quads and bricks). In the equation you've presented, I'd guess that Ae is the area of a 2D element, and SQRT (Ae) gives the length of the side of a square with the equivalent area. The alpha factor apparently accounts for the distance between the nodes of the element. I'm not sure why
