RSL2Potential¶
- class RSL2Potential(particleType1, particleType2, a, b, c, r_cut=None)¶
Constructor of the potential.
- Parameters:
particleType1 (ParticleType or ParticleIdentifier) – Identifier of the first particle type.
particleType2 (ParticleType or ParticleIdentifier) – Identifier of the second particle type.
a (PhysicalQuantity of type energy) – Potential parameter.
b (PhysicalQuantity of type length**-1) – Potential parameter.
c (PhysicalQuantity of type length) – Potential parameter.
r_cut (PhysicalQuantity of type length) – The cutoff radius of this potential.
- classmethod getAllParameterNames()¶
Return the names of all used parameters as a list.
- getAllParameters()¶
Return all parameters of this potential and their current values as a <parameterName / parameterValue> dictionary.
- static getDefaults()¶
Get the default parameters of this potential and return them in form of a dictionary of <parameter name, default value> key-value pairs.
- getParameter(parameterName)¶
Get the current value of the parameter parameterName.
- setParameter(parameterName, value)¶
Set the parameter parameterName to the given value.
- Parameters:
parameterName (str) – The name of the parameter that will be modified.
value – The new value that will be assigned to the parameter parameterName.
