The DBS file parameter imode is used to control the simulation mode. This option is set to 1 for steady-state simulation.

The first step in model creation and testing is a steady state simulation. Steady state model simulations are employed to converge new model units, verify relationships between key process variables, and allign process values to typical operating regions. The SS (#1) and RTO (#3) modes are used to obtain an initial condition solution for all other modes of operation. The initial condition files rto.t0 and ss.t0 override default values given in the apm file.
