Hi,
Applying displacement as a BC instead of Force aids in convergence as specifying displacement means the solution is defined at each time point, making it easier to converge. On the other hand, when a force is applied, the program may struggle to solve the case if the connection slips, as there is no stiffness to carry the load.
See if this post on similar issue helps: Inputting displacement to get reaction force results work but not the other way (ansys.com)
Thanks,
