Table 6-70: Time parametric Properties Name of the controlling study step or "user" if the feature is controlled manually. on | off on | off List of parameter values. Obsolete, use plistarr instead. sparse | filled Method for doing the parameter variation. For sweeptype=sparse, the parameter tuples defined by the columns in plistarr are solved for. This method requires equal length for the rows. For sweeptype=filled, all parameter combinations given by plistarr are solved for.
