Thanks for your reply, Sir
As you told me, contact elements are not allowed in the crack mesh region, so can I use the submodeling analysis technique? I tried that technique and cut a portion of the fracture zone. And perform the analysis (I have attached a picture of the cut portion).
Here, I used the cut boundary constraints conditions for the sub-modeling. But now I am getting the two problems
1) Getting very high stresses, which is out of range
2) The fracture problem is solved only in the single substeps. As I increase the sub-steps, it gives the error.
Please help me with this.
