Control cards allow you to add input and output parameters to a model, including location and names of the input, output and scratch files; the type of run (analysis, check or restart); overall running of the analysis or optimization; and type, format and frequency of the output.

Control cards are assigned to your model from within the Control Cards panel. This panel lists all of the control cards defined for the solver/user profile that you currently have loaded; you can disable, enable, or delete cards as desired.
