Error termination for LS-TASC optimization
I am running a topology optimization simulation for an impact problem in LS-TASC and my simulation terminates after 5th iteration and the log file (joblog) says that the nodes referred to in the node-set do not exist. I believe LS-TASC has deleted certain elements and nodes that is why they don't exist but it should be similar in other iterations as well I guess. I have attached the log file screenshot for reference. Can someone help me resolve this error? Any help is appreciated!
(I did try reducing the impact velocity but it didn't help).
