I am getting this message in my 5th calculation phase.
the phase was running OK before i did some changes in the model.
No clue about the error or problem area.
Dear Sharique,
According to Reference manual, Appendix J:
First of all, I recommend looking at those elements that first appeared in Phase 4 (geometry and properties of these elements).
If it does not help I suggest you submit a service request. One of PLAXIS support engineers can help you in detail:
