How to determine initial conditions for subset of Simulink blocks that have underspecified initial conditions
Model Configuration Pane: Diagnostics / Data Validity
Description
The Unspecified initialization detection parameter specifies how the software determines the initial conditions for blocks that have underspecified initial conditions. The software determines the initial condition for conditionally executed subsystems, Merge blocks, subsystem elapsed time, and Discrete-Time Integrator blocks when the model does not fully specify the initial conditions.

Version History
Introduced in R2008b
The classic initialization mode will be removed in a future release. Use the simplified mode instead. Simplified mode helps to avoid unexpected simulation results and improves consistency. For more information about how to switch from classic to simplified initialization mode, see Convert from Classic to Simplified Initialization Mode.
