Dear users<div> In my calculation with carbon chain between 9 to 12 carbon atoms I have to include Van der walls interaction and I am not clear about it's inclusion in DFT. What all are the key words and parameters for that and how effective is the implementation? Can anyone shed some light in to this. </div>
