1. A computer-implemented method, comprising:
providing a numerical simulation mesh comprising a plurality of nodes; and
performing a numerical simulation of a solid material using the mesh and a user-selectable transition threshold associated with a cohesive zone model traction-separation relation; and
comparing local material states of the mesh to the user-selectable transition threshold during the performing the numerical simulation to determine whether to insert cohesive elements in the mesh;
wherein the cohesive elements are not included at an initiation of the numerical simulation.
