[TRNSYS-users] How to skip timesteps if they don't reach convergence?

Hello TRNSYS users,
I've noticed that some simulations finish with messages that say that a
certain component (or components) doesn't reach convergence at certain
timesteps. The message is the following:
" The inputs to the listed units have not converged at this timestep. The
values at the last iteration will be used and the simulation will proceed."
Right now I'm doing a simulation with 5 min timestep that works well but
gets stuck at hour 150, for example. If I change the simulation start time
everytime this happens so the simulation can continue, it keeps calculating
until it gets stuck again 200 hours later.
I assume the TRNEXE gets stuck because of non convergence. Since the non
converged timesteps are neglectable, how can I set TRNSYS to automatically
ignore this timesteps and set the input/ouputs of the problematic units to
the previous ones?
Is there a chapter in the TRNSYS Documentation that I should check?
Thanks in advance,
Javier Vega
