The unit number is a unique integer that corresponds to a single model in an project. To see the Unit number within the Studio, press the F2 key. You may also open the input file or the list file and see the unit numbers. Typically convergence problems are caused by:
1) too big of a time step
2) not enough capacitance in a flow loop
3) poor controls
4) improper connections

I am getting a large number of convergence warnings. As I understand, this means that the outputs of certain components are not stabilizing to specific values at individual time steps. How can I figure out which components are not converging? It reads Type "0" and Unit "0" next to each warning message in the log. Each warning ends with "Reported information: UNITS: 12 13 14 17", but I can't figure out what this means (what is Unit number?).I have tried using the TRACE feature, but without knowing where to start looking within the list file, it is hard to figure out what isn't converging. Thanks.
