Details

DescriptionThis measure extracts key simulation results and performs basic model QAQC checks. Each category of checks provides a description of the source of the check. In some cases the target standards and tollerances are adjustable.
Modeler DescriptionReads the model and sql file to pull out the necessary information and run the model checks. The check results show up as warning messages in the measure's output on the PAT run tab.
