I’ve found that when I use several CPUs with the SMP code that only one CPU is working and the other CPUs are idle. What is the problem and how can it be corrected?

In the forming analysis, sometimes when the mesh is distorted, the slave node is pushed too far away from its previous step, and at this time, the contact-searching algorithm cannot find the necessary information. In this case, it is possible to have a dead loop for this contact search process.

When the dead-loop happens, the only solution is to stop it and check the input deck to see if there is any problem in it.
