Struct MorsePotential

pub struct MorsePotential {
    pub radius: f64,
    pub potential_stiffness: f64,
    pub cutoff: f64,
    pub strength: f64,
}

Famous Morse potential for diatomic molecules.

Parameters & Variables

Symbol	Struct Field	Description
$R$	radius	Radius of the particle
$\lambda$	potential_stiffness	Can be interpreted as the inverse width of the potential
	cutoff	Cutoff after which the interaction strength is identically 0
$V_0$	strength	Interaction strength
$r$		Distance between interacting particles

\begin{equation} V(r) = V_0\left(1 - \exp\left(-\lambda(r-R)\right)\right)^2 \end{equation}

Trait Implementations

impl Clone for MorsePotential

fn clone(&self) -> MorsePotential

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MorsePotential

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MorsePotential

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<const D: usize> Interaction<Matrix<f64, Const<D>, Const<1>, ArrayStorage<f64, D, 1>>, Matrix<f64, Const<D>, Const<1>, ArrayStorage<f64, D, 1>>, Matrix<f64, Const<D>, Const<1>, ArrayStorage<f64, D, 1>>, f64> for MorsePotential

fn get_interaction_information(&self) -> f64

Get additional information of cellular properties (ie. for cell-specific interactions). For now, this can also be used to get the mass of the other cell-agent. In the future, we will probably provide a custom function for this.

fn calculate_force_between( &self, own_pos: &SVector<f64, D>, _own_vel: &SVector<f64, D>, ext_pos: &SVector<f64, D>, _ext_vel: &SVector<f64, D>, ext_info: &f64, ) -> Result<(SVector<f64, D>, SVector<f64, D>), CalcError>

Calculates the forces (velocity-derivative) on the corresponding external position given external velocity. By providing velocities, we can calculate terms that are related to friction. The function returns two forces, one acting on the current agent and the other on the external agent.

fn is_neighbor( &self, own_pos: &Pos, ext_pos: &Pos, ext_inf: &Inf, ) -> Result<bool, CalcError>

Checks if the other cell represented by position and information is a neighbor to the current one or not.

fn react_to_neighbors(&mut self, neighbors: usize) -> Result<(), CalcError>

Reacts to the results gathered by the [Interaction::is_neighbor] method and changes the state of the cell.

impl IntoPy<Py<PyAny>> for MorsePotential

fn into_py(self, py: Python<'_>) -> PyObject

Performs the conversion.

impl PartialEq for MorsePotential

fn eq(&self, other: &MorsePotential) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PyClass for MorsePotential

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for MorsePotential

const IS_BASETYPE: bool = false

#[pyclass(subclass)]

const IS_SUBCLASS: bool = false

#[pyclass(extends=…)]

const IS_MAPPING: bool = false

#[pyclass(mapping)]

const IS_SEQUENCE: bool = false

#[pyclass(sequence)]

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<MorsePotential>

This handles following two situations:

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.

Checks if object is an instance of this type or a subclass of this type.
