Detailed Description

The derived class from initial to impose random initial condition for channel flow.

Constructor & Destructor Documentation

channelRand()

channelRand::channelRand

(

const grid &

mesh

)

Constructor of the initial class.

     The empty constructer merely initializes the local reference to the global mesh variable.

Parameters

mesh	is a const reference to the global data contained in the grid class

Member Function Documentation

initializeField()

void channelRand::initializeField ( vfield &  uField )

virtual

Function to impose random initial condition for channel flow on the given input velocity field.

     The function generates random values for the entire domain (with independent seeds for individual ranks).
     The random values are scaled by multiplying with an inverse parabola and then added to the mean velocity field.
     The mean field is assumed to have value 1.0

Reimplemented from initial.
