Class BoundaryCondition

Defined in Program listing for file kernel/src/modelingTools/BoundaryCondition.hpp

class BoundaryCondition

This class models simple boundary conditions for prescribing the velocities in a Dynamical System.

A simple boundary condition is considered to fix a component \( j \) of the velocity vector, i.e., \( v_j(t) = bc(t) \) where \( bc(t) \) is a given function of time.

Public Functions

BoundaryCondition(SP::UnsignedIntVector newVelocityIndices)

Basic constructor.

Parameters:

newVelocityIndices – the indices of the velocity subjected to prescribed velocities

BoundaryCondition(SP::UnsignedIntVector newVelocityIndices, SP::SiconosVector newVelocityValues)

Constructor with constant prescribed values.

Parameters:

• newVelocityIndices – the indices of the velocity subjected to prescribed velocities

• newVelocityValues – the values of the prescribed velocities

virtual ~BoundaryCondition()

destructor

inline SP::UnsignedIntVector velocityIndices()

to get the velocityIndices

Returns:

a pointer on _velocityIndices

inline SP::SiconosVector prescribedVelocity()

to get the prescribedVelocity

Returns:

a pointer on _prescribedVelocity

inline SP::SiconosVector prescribedVelocityOld()
