After running the model, the results fields show as N/A


1) Ensure that the model computed successfully and that there are no red user notifications showing. You can sort the table on ID or name if red notifications do not show at the top. In almost all cases, a red notification indicates a data entry issue that stopped the calculation from completing, in which case the results are not saved and show as "N/A". Use the Validate tool to get a full list and resolve the red messages before attempting to compute the model.

2) Ensure that you are looking at a result field that is applicable to the type of calculation or solver being used. In some cases a result field my not be applicable in every case. If other, basic results are showing, then most likely the "N/A" results you see mean that they are not applicable for the current solver and analysis type, or configuration of the element.

3) If you are running a fireflow analysis and looking at fireflow results in the fireflow flextable, the elements may not be included in the selection set used for "fire flow nodes" in the fireflow alternative, or the calculation has failed because one or more nodes violated fireflow constraints before any fireflow is added (which stops the run) - see your User Notification List.

4) If the above does not help, use the Compact Database tool (For CONNECT Edition and greater this is under File > Database Utilities. For V8i and under, this is under Tools > Database Utilities. Lastly, re-compute the model.
