Variable Initialization

Initialize block variables prior to simulation and verify results

The Simscape™ solver computes the initial conditions for model simulation by finding initial values for all the system variables to satisfy all the model equations. You can affect the initial conditions computation by specifying the priority and target initial values for block variables. You can also initialize variables for a whole model from a saved operating point. After you initialize the block variables and prior to simulating the model, you can open the Variable Viewer to see which of the variable targets have been satisfied.

Functions

simscape.op.createCreate operating point by extracting data from model or from logged simulation data
simscape.op.OperatingPointOperating point object containing hierarchical target data for variable initialization
simscape.op.TargetVariable initialization target object
