Detailed Description

Curvature induced separation film to cloud ejection transfer model.

Assesses film curvature via the mesh geometry and calculates a force balance of the form:

F_sum = F_inertial + F_body + F_surface_tension

If F_sum < 0, the film separates and is transferred to the cloud if F_sum >= 0 the film remains attached.
