you can use CONWEP in interaction module. CONWEP function enables you to choose amount of used TNT in explosion

 Thank you from your guidence.

Isn't there any way for modelling TNT ?

I think CONWEP is for surface blast. My blast is in underground.

But i think we cannot model TNT in abaqus the way LS-DYNA uses. u just give the amount of equivalant TNT and abaqus handles it
