yes Mostapha, 

you can use Gaussian09 ou Gaussian03 to do your density functional theory (DFT) calculations with Gaussview.

For DFT calculation, you can use Gamess, Qchem,Dmol or Gaussian software. As suggested by Hadji Djebar, Gaussian is superior than other.

Dear Dr. Gour and dear Djebr,

is this software free? and how can I get it?

and Do you have any tutorial for DFT calculation?

Hi Mostafa,

Gaussian is not free.

You should look for computer chemists at your university, ask if Gaussian is available, and check the following tutorials:

Dear Dr. Ishikawa

Thanks for your kindly answer.

I found this software thanks to your guide.

and the tutorials were also helpful.

Dear Mostafa

Firefly is a freely available computational chemistry program.

As I know, VASP may do that job, but it will time-consuming very much.

Dear Sadiq,

Thanks for your Kindly response.
