Running models: diagnostic dialogues

The point at which you attempt to run a newly built model is where you are most likely to encounter failures due to incompleteness or inconsistencies in the model's definition. You should not give up at this point; a bit of attention to the messages will enable the problems to be fixed.

The first dialogue that appears will have an outline description of the problem, and only two buttons. Depending on the nature of the problem, these can be:

  • OK / More info...

The problem has stopped whatever task was in progress from being completed. You can hit "OK" to go back and try again, or "More info..." to see a more detailed message, and get a reference to these help pages where appropriate.

  • Give up / See all...

The task in progress can continue, although it will not be successfully concluded. You can hit "Give up", fix the indicated problem and try again, or "See all..." to keep running the task and display a list of all the problems found at the end.

  • Default option / More options...

There are several possible actions that can be taken at this point. The most frequently chosen is named on the left button, while the right button opens another dialogue displaying all the options.

 

For example, the above is the "Some parameter values unused" dialogue.  If a parameter metafile contains parameterization information relating to components that do not exist in the model you are trying to run, you have four options: Discard values (the default: ignore values for the missing component and keep loading the rest of the data), Give up, Use elsewhere (find a model component with a different name that can take the values for the missing one) or see help. The initial dialogue offers only the "Discard values" option and "More options...". Choosing the latter brings up the dialogue displayed above.

The Use elsewhere button is useful in the case where you have changed the name of a model component or a submodel containing it, or added or deleted a submodel boundary around it, since saving the parameter metafile. In the case above, the dialogue is pointing out that some parameters are for a component in a submodel that no longer exists in the model. In this case, hitting Use Elsewhere will bring up a tree diagram showing all the submodel captions in your model, and their nesting relation. When you select a submodel from this list, Simile will try to find the components from the lost submodel in that submodel instead, and supply the parameter data to them. If this works, you should re-save the parameter metafile later to avoid having to do the same thing again next time you open the model.
