Following is my code...

#include <iostream>
#include <cmath>
#include <cstdlib>
#include "domain.h"
#include "preprocess.h"


using namespace std;

int main(){

        Domain* pdomain;
        int size = 100;
        int total_nodes =size*size;
        int dims = 2;
        int nz = 1;
        double tau = 0.6;
        double rhozero = 1.0;
        int timemax = 100000;
        Input_st* pInput_ar;
        pInput_ar = (Input_st*) Preprocess(size, size, nz, pInput_ar,
"config_data.txt");       

        //DeallocateInputArray(pInput_ar);      
        DisplayInputArray(pInput_ar, total_nodes);      


        pdomain = new Domain(dims, size, size, nz, tau, rhozero);

        pdomain->InitializeDomain(pInput_ar, total_nodes);

        pdomain->DisplayDomain();


        for(int t=0; t<timemax; t++) {  
                pdomain->SimulateDomain();
                pdomain->DisplayDomain();                               
                if(t%100 == 0){         
                        pdomain->DisplayDomain();
                        cout<<t<<endl;  
                }
        }



        //pdomain->PostProcess();

        //pdomain->ConstructDomain()



        //Lattice_Abc* pLattice = new Lattice_D2Q9();
        // Lattice_Abc* qLattice = new Lattice_D3Q19();
        /*
        Node*** mpNode;
        mpNode = new Node**[nz];
        for(int z=0; z<mNz; z++){
                mpNode[z] = new Node*[mNy];
                for(int y=0; y<mNy; y++){
                        mpNode[z][y]= new Node[mNx];
                }
        }*/


        /*
        Pdfs_Abc* pPdfs = new Pdfs_Solid();
        pPdfs->DisplayPdfs(pLattice);
        double density=2.0;
        Pdfs_Abc* qPdfs = new Pdfs_Fluid(qLattice,density);
        qPdfs->DisplayPdfs(qLattice);
        */
        //Lattice_Abc* & rpLattice = pLattice;
        //Lattice_Abc** ppLattice= & pLattice;
        //rpLattice->DisplayLattice();
        //(*ppLattice)->DisplayLattice();

        /*

        pLattice->DisplayLattice();
        int & speeds = pLattice->Speeds();
        cout<<"speeds\t"<<speeds<<endl;

        //Moments_Abc* pMoments = new Moments_Fluid();
        double vel[2] = {1.0, 0.0};
        double density =1.0;
        int nodetype =21;

        //Moments_Abc* pMoments = new Moments_Fluid(pLattice, density, vel,
nodetype);
        //pMoments->DisplayMoments(pLattice);

        //Moments_Abc* qMoments = new Moments_Fluid(qLattice, density, vel,
nodetype);
        //qMoments->DisplayMoments(qLattice);

        Moments_Abc* pMoments = new Moments_Solid(pLattice, density, vel,
nodetype);
        pMoments->DisplayMoments(pLattice);

        Moments_Abc* qMoments = new Moments_Solid();//(qLattice, density, vel,
nodetype);
        qMoments->DisplayMoments(qLattice);

        */

        cout<<"\nend of main"<<endl;
}




So where I am wrong.
