Model update set workflow

Step	Summary	Detailed help topics
1.	Create at least two Model Update solution processes.	The Model Update solution process references a work solution and a reference solution.	Create a Model Update solution processEdit the Model Update solution process
3.	Create the Model Update Set solution process.	The Model Update Set solution process combines multiple Model Update solution processes to simultaneously optimize different configurations of the same model.	Create a Model Update Set solution process
4.	Review design variables.	The Model Update Set solution process contains the union of the constituent Model Update solution process design variables. You can:Modify design variable values, bounds, and individual weights. When you create a Model Update Set solution process, the values and status of common variables are derived from the master Model Update solution process.Fix design variables that you do not want to change during optimization.Reset the design variable values and bounds from the current constituent Model Update solution processes.	Modify a design variableRemove a design variable from the optimizationReset the design variables
5	Specify the optimization targets.	The Model Update Set solution process lets you:Modify the individual weights of the optimization targets.Activate or deactivate targets for optimization.Reset the target configuration.Set the target pairing method.	Modify individual target weightModify the mode pairing and shape correlation methodReset targetsActivate or deactivate targets from the optimization
6.	Compute the errors.	The Model Update Set solution process computes initial and current errors for both frequency and mode shape targets.	Solve for target errors
7.	Optimize the design variables.	The Model Update Set solution process lets you choose between the following optimization algorithms:Least squareSteepest descentGenetic algorithmAfter optimization, the solver renews the design variables of the constituent Model Update solution processes with the updated design variable values.	Launch the optimization
8.	Review the errors and design variables.	Lets you verify:The effectiveness of the optimization in reducing overall and individual target errors.The change in the design variables values.
9.	Update the design variable modeling objects.	You update the initial values of the design variable modeling objects in the Simulation file with the current design variables of the active Model Update Set solution process.	Update the design variables
10.	Resolve the work solutions.	Resolves the SOL 200 Model Update solution work solution of each constituent Model Update solution process.	Solve the work solution during the Model Update solution process
11.	Refresh the results of the Model Update Set solution process.	Refreshes all constituent Model Update solution processes and recomputes the Model Update Set errors without updating the design variables.	Refreshing model update and model update set results
12.	Repeat steps 8 — 11 until you are satisfied with the current target errors and design variable values.
13.	Update the FE model.	The current design variables of the active Model Update Set solution process are used to update the material and physical properties, in the FEM or Simulation file, which are referenced by the design variable modeling objects. The initial values of the design variable modeling objects in the Simulation file are set to 1.0.	Update the FE model
14.	Reset the design variables	The Model Update Set solution process design variable values must reflect the values of the Simulation file's modeling object, which is equal to 1.0 after updating the FEM.	Reset the design variables
15.	Repeat steps 10 and 11.
