Design optimization workflow

Step	Summary	Detailed help topic
1.	Create a FEM file and Simulation file.	Make sure that the model has a mesh.	Create new FEM and Simulation files
2.	Create a design optimization solution and subcase.	Set Solver to Simcenter Nastran, set Analysis Type to Structural, and set Solution Type to SOL 200 Design Optimization.Make sure that the design optimization solution has at least one subcase.	Create or modify a solution
3.	Create a design objective and response.	When you create or edit a design optimization solution, you can specify the objective and response, such as minimizing the weight of the model.	Create the design objective and response
4.	Create the design variables.	When you create or edit a design optimization solution, you can define the allowable changes to your finite element model.For example, you might allow a shell element thickness to vary from 0.1 inches to 1.2 inches.	Create a design variable for design optimization
5.	(Optional) Specify any design optimization parameters.	When you create or edit a design optimization solution, you can control the frequency or level of detail in the optimization output.	Control the design optimization outputOptimization spreadsheet
6.	Create any additional subcases and add design constraints.	The design optimization solution can have multiple subcases, such as a linear statics subcase and a normal modes subcase.Each subcase can have its own design constraints. For example, you can specify the allowable X-displacement values at a specific node for a linear statics subcase, or the first frequency value for a normal modes subcase.Make sure that each subcase has at least one load and constraint.	Create design constraints and responses
7.	Solve the model.	The software adjusts the design variables while working toward the design objective and observing the limitations of the design constraints.	Solve the model
8.	Examine the optimization results.	You can examine the optimization results in the Post Processing Navigator, view data about the design objective and design variables in the optimization spreadsheet, or review the Simcenter Nastran .f06 file.
