Steady State

Steady State is a concept used in the Models Step in ASCMO-MOCA for following model types:

• FMU models
• Simulink models
• TSiM PlugIn

It can only be applied if the imported data is static. This can be checked in the Data Step (Data Sampling: Static (no time)).

Steady state is a state in which all relevant variables are constant relative to each other over time or grow at the same rate (steady development). That means the state of equilibrium. 3 sizes can be specified.

• Simulation Step Size: Define the simulation step size (base sample time). This is specified in the model and must match.

• Time until Steady State: This is the time span to wait until steady state is reached (worst case scenario).

• Average Last: Defining the duration of the average interval at the end of Time until Steady State phase. Enter time in seconds to average the last values and determine a mean value.
