Use the Model Data Window

The Model Data window is a powerful tool for reviewing and documenting model inputs, along with finding input errors in a model.

Look at the model in Figure 1. If an input error in one of the pipes was suspected, the task of looking for the error in each individual pipe input window would be tedious.

Now look at the Model Data window for the pipes in Figure 2. Here it is much easier to scan down columns of data looking for input errors. In this case, one of the pipe lengths was accidentally entered in miles rather than feet.

Figure 1: Workspace layout of a pipe system with an input error in one of the pipes (error not shown).

Figure 2: Model Data window display for the model in Figure 1. From this perspective it is much easier to see that one of the pipes (#2) has length data entered in miles rather than feet. This is not automatically an input error, as AFT xStream accepts pipe input with mixed engineering units. However, more frequently than not the user intends to use consistent units, so this probably is an error.
