how to calculate of curvature(differentiation of normal vector)

Please login with a confirmed email address before reporting spam

Hi.

Can we calculate of curvature of geometry boundaries in 2D?

In other words, can we get differentiation of normal variables(nx,ny)?
We define the curvature K as "K = dnx/dx + dny/dy".

We want to use the curvature K or the differentiation of normal variables in PDE physics.

Thanks.
