how to creat cohesive element with optistruct

Hi, there is a question I would like to ask the teachers, recently learn to use optistruct for composite material optimization design, encountered some unsolvable problems, I want to use the cohesive element to simulate the cementation damage between the composite layers, but there is no cohesive material in the hypermesh. There is no such material property, no damage evolution rule and damage criterion of the cohesive element. There is a cohesive element in the hypermesh-abaqus interface, but I don't know how to call it in the optistruct. So,is there any methods to solve this ,could you give me a reply .best wishes.
