It is possible to force a time step to converge. This can be done by interrupting the run (using ctrl+c) and then enter the conv command at the FEBio prompt. This will force the time step to converge and FEBio will continue with the next time step. This is not a recommended practice as the solution may become unstable and in fact it is unlikely that FEBio will be able to converge any of the following time steps. However, it can be useful in some scenarios. For example, if there is no load applied in the initial time step and FEBio has trouble getting past this initial step (see Section 8.3.2.1↑) or when you want to store the current state to the plot file without having to rerun the problem in debug mode (although the plot command or debug command might be better alternatives).
