Dear colleaugues,
I was looking for ways of calculating the radius of curvature of a deforming boundary in 2D model (in time dependent solid mechanics module).
i tried to use the equations derived for two fucntions of time i.e. u = u(t) and v=v(t) ,
Rad of curv = ((ut^2+vt^2)^1.5 )/(ut*vtt +vt*utt)
but this equation give me very noisy values which are bad for my solver. do u have any other suggestion to deal with this kind of problem?
Thanking you in advance
