Delamination using cohesive interaction

Hello,

Im trying to simlate delamination in abaqus and after going through the documentation i decided to go for the cohesive element approac. In the documentation it is mentioned that we use a general contact(explicit) for the interation but when i do that i am unable to use general, static step. So which step do i go for if i i want to simulate a static delamination ?

-For the initial crack i left a certain region unbounded and used a double cantilever model.
