Dear John,

Thank you very very much for your advice! Sorry for the late reply because I did not notice there was a reply to my post.

I found this sample command snippet provided by you in one of my other posts to post process the CZM debonding parameters.

***********

set,last

esel,s,type,,cid1                                !select contact element type ‘cid1’

etab,dtstart,nmisc,66                     !load step time during debonding

etab,dparam,nmisc,70                   !debonding parameter

etab,deneri,nmisc,140                   !debonding parameter

pretab,dtstart,dparam,deneri     !print results to solver output

pletab,deneri                                     !plot critical fracture energy

I am really new to APDL command and I have to humbly ask a few studpid questions if you don't mind... 

1) Do I have to insert a APDL command snippet to name the czm bonded contact for which I want to investigate? I am asking because there are 18 different CZM bonded contacts in the model.

cid=czm1 ! Define the name of this CZM bonded contact is "czm1" 

2) After the name of the contact is defined, I just need to change the 2nd row of the sample command to:

esel,s,type,,czm1

Is this correct?

3) I reviewed the ETABLE commands and as well as the Table 174.2 and 174.3.

I don't really understand what EIJKL means, so do I have to change the numbers 66, 70 and 140 in the command? 

4) Forgive one more stupid question. The solution has already stopped. Following Question 1, I guess if I were to add a APDL command snippet under one of the czm contact to define cid name, do I have to solve it again? because it took a long time to run the model....Shall I insert this sample command snippet under "solution" or "analysis" section?

Looking forward to your guidance!

Kind regards,
