Surface Curvature Range - Units?

Altair Forum User

In the surface curvature interface, the min and max range can be specified.  What units are used?  Is it radians/unit or something else?

Also - can the color scale be modified?

Hi Steve,

In general, curvature of a curve is 1 / r, where r is the radius of the osculating circle (the best approximating circle)
so, in case of cm as current unit, it should be 1 / cm and in case of a surface, you have two curvatures, in two different directions, say k1 and k2
mean curvature is just 0.5 * (k1 + k2) , so the unit should be 1 / cm

We are going to refine this tool in 2018 and add some much needed clarity.
