void computeFrictionForce()
Computes nothing, it is an empty function.
Mdouble getTangentialOverlap() const override
Returns zero overlap.
double Mdouble
Definition: GeneralDefine.h:34
~EmptyFrictionInteraction() override
Destructor.
EmptyFrictionSpecies is used to create a force law without frictional forces.
In case one wants to have a frictionless interaction between the interactables (particles or walls)...
Stores information about interactions between two interactable objects; often particles but could be ...
void write(std::ostream &os) const override
Interaction write function, which accepts an std::ostream as input.
void read(std::istream &is) override
Interaction read function, which accepts an std::istream as input.
BaseFrictionForce * getFrictionForce() const
Definition: BaseSpecies.h:150
const BaseSpecies * getBaseSpecies() const
Return a constant point to BaseSpecies of the interaction.
const EmptyFrictionSpecies * getSpecies() const
Returns a const pointer of type EmptyFrictionSpecies*.
void integrate(Mdouble timeStep) override
Does nothing as there is no force.
#define UNUSED
Definition: GeneralDefine.h:39
Defines the basic properties that a interactable object can have.
Definition: Vector.h:49
std::string getBaseName() const
Returns interaction name/type.
const Vec3D getTangentialForce() const override
Returns zero tangential force.
Mdouble getElasticEnergy() const override
Returns zero as it is an frictionless interaction.
