Thank you. But can we get the strain energy release rate at each nodal point like we get in VCCT? I am doing a comparative study of two techniques, VCCT and CZM of 3D composite DCB and a standard plate specimen . In VCCT i have directly got the values of energy release rates in visualization tab with field outputs ENERT and ENEER1,2 and 3 for each node. But when i call for the same field output in CZM method the values of all energy release rates are zero irrespective of the loads or displacements applied. So my question is ,is there any way where we can get the values of energy release rate in CZM similar to VCCT for each node? Please let me know as i am stuck with the extraction of energy release rate results since a long time. Thanks in advance.
