<p>TRNSYS will iterate until the iteration limit is reached, write a warning message to the list file, and then continue on to the next timestep. When you say TRNEXE gets "stuck" what do you mean?</p>

<div dir="ltr">Hello TRNSYS users,
<div> </div>
<div>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:</div>
<div> </div>
<div>" 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."</div>
<div> </div>
<div>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.<br /><br /></div>
<div>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?</div>
<div> </div>
<div>Is there a chapter in the TRNSYS Documentation that I should check?</div>
<div> </div>
<div>Thanks in advance,</div>
<div>Javier Vega</div>
