# Class FixedBC¶

class FixedBC : public BoundaryCondition

This class models a simple fixed 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., $$v_j(t) = 0$$

Public Functions

FixedBC(SP::UnsignedIntVector newVelocityIndices)

Basic constructor.

Parameters

newVelocityIndices – the indices of the velocity subjected to prescribed velocities

virtual ~FixedBC()

destructor

virtual void computePrescribedVelocity(double time)

default function to compute the precribed velocities

Parameters

time – : the current time
