SmoothCircleIC

Circle with a smooth interface

Insert a single disk or sphere with radius (radius) and a smooth interface of width (int_width) with a user specified value range and functional dependence of the interface (profile). (outvalue) is the variable value outside of the disk/sphere and (invalue) is the value on the interior.

Cosine profile (COS)

Hyperbolic tangent profile (TANH)

(1)

In both cases is the initial condition value at , where is the center point (x1, y1, z1) of the circle (making a radius vector).

The hyperbolic tangent interface is scaled to have the same slope at its midpoint as the cosine interface.

For the COS interface, which is strictly zero outside the particle and strictly inside the particle the interface width int_width denotes exactly the width of the transition region where the order parameter values are in the open interval . The TANH interface function is asymptotic and requires a different definition for the interface width. Here we chose to have the slope at the midpoint match up with the midpoint slope of the COS interface (giving rise to the factor of in eq. Eq. (1)).
