Cannot creating new double*

[mormech]

Hi,
This code while creating 'u' have an error.
Please Help me.

  #include <math.h>
#include <fstream>
#include <iostream>
using namespace std;
#define pi 3.1415

int main()
{
	int N,i,size,j,n;
	double mesh,T,end;
	cout << "Welcome To Wave Equation Solution Program\nPlease Enter the size of the Mesh(for Example:0.01):";
	cin >> mesh;
	cout << "Please Enter the Time Finish Step:";
	cin >> T;
	N = (int)T/mesh;
	size = (int)200 / mesh;
	cout <<endl<<N<<"\n"<<size;
	double***u;
	u = new double**[N];
	for (i = 0; i < N; i++)
	{
		u[i] = new double*[size];
		for (j = 0; j < size; j++)
		{
			u[i][j] = new double[size];
		}
	}		
	cin>>end;
	return 0;
}

Thanks.
