◆ tfPotential_create_overlapping_sphere()

HRESULT tfPotential_create_overlapping_sphere	(	struct tfPotentialHandle *	handle,
		tfFloatP_t *	mu,
		tfFloatP_t *	kc,
		tfFloatP_t *	kh,
		tfFloatP_t *	r0,
		tfFloatP_t *	min,
		tfFloatP_t *	max,
		tfFloatP_t *	tol )

Creates an overlapping-sphere potential from :cite:Osborne:2017hk.

The overlapping-sphere potential has the form:

$\mu_{ij} s_{ij}(t) \hat{\mathbf{r}}_{ij} \log \left( 1 + \frac{||\mathbf{r}_{ij}|| - s_{ij}(t)}{s_{ij}(t)} \right) \text{ if } ||\mathbf{r}_{ij}|| < s_{ij}(t) ,$

$\mu_{ij}\left(||\mathbf{r}_{ij}|| - s_{ij}(t)\right) \hat{\mathbf{r}}_{ij} \exp \left( -k_c \frac{||\mathbf{r}_{ij}|| - s_{ij}(t)}{s_{ij}(t)} \right) \text{ if } s_{ij}(t) \leq ||\mathbf{r}_{ij}|| \leq r_{max} ,$

$0 \text{ otherwise} .$

Osborne refers to $\mu_{ij}$ as a "spring constant", this controls the size of the force, and is the potential energy peak value. $\hat{\mathbf{r}}_{ij}$ is the unit vector from particle $ i $ center to particle $ j $ center, $ k_C $ is a parameter that defines decay of the attractive force. Larger values of $ k_C $ result in a shaper peaked attraction, and thus a shorter ranged force. $s_{ij}(t)$ is the is the sum of the radii of the two particles.

Parameters

handle	Handle to populate
mu	interaction strength, represents the potential energy peak value. Defaults to 1.0.
kc	decay strength of long range attraction. Larger values make a shorter ranged function. Defaults to 1.0.
kh	Optionally add a harmonic long-range attraction, same as :meth:`glj` function. Defaults to 0.0.
r0	Optional harmonic rest length, only used if `kh` is non-zero. Defaults to 0.0.
min	The smallest radius for which the potential will be constructed. Defaults to 0.001.
max	The largest radius for which the potential will be constructed. Defaults to 10.0.
tol	The tolerance to which the interpolation should match the exact potential. Defaults to 0.001.
