Curvature Calculation
 
I am trying to calculate the curvature of the liquid-vapor interface, which is given by:

\kappa = \nabla . n

n = interface normal given by the ratio of the volume fraction gradient to its magnitude.

How would one calculate the "divergence" of the normal vector?

hello,

You can refer to paper of BRACKBILL' paper (1991)
