    A Comparison Principle for the Mean Curvature Flow Equation with Discontinuous Coefficients by Cecilia De Zan, Pierpaolo Soravia

    Published 2016-01-01
    “…We study the level set equation in a bounded domain when the velocity of the interface is given by the mean curvature plus a discontinuous velocity.

    Newton Linearization of the Curvature Operator in Structured Grid Generation with Sample Solutions by Pat Piperni, Maahi M. Talukder

    Published 2022-01-01
    “…This new operator retains the strong smoothing properties of the Laplacian without the latter’s adverse curvature effects. However, the new operator exhibits slower convergence properties than the Laplacian, which can lead to increased turnaround times and in some cases preclude the achievement of convergence to machine accuracy. …”
