"Surface based COHESIVE BEHAVIOR cannot be used for contact pair interactions. See the surface interaction named INTPROP-2" is shown when I do the data check for my model. I can't really make sense of this and much appreciate some help with it.
I am trying to model a traction-separation interface between layers of 3D printed concrete in a 3-point bending test. The model is shown below in section. It is symmetrical.
