Design sensitivity analysis workflow

Step	Summary	Detailed help topic
1.	Create a FEM file, Simulation file, and design sensitivity analysis (DSA) solution.	Make sure that the model has a mesh.When you create the solution:Set Solver to Simcenter Nastran or MSC NastranSet Analysis Type to Structural or Vibro-AcousticSet Solution Type to SOL 200 Design Sensitivity Analysis.You can also specify how to handle the design sensitivity output and which parameters to apply.	Create new FEM and Simulation filesCreate a design sensitivity analysis solution
2.	Create a design constraint.	Design constraints can include the model's volume, weight, normal modes, and modal frequencies.If you do not create a design constraint for the solution, you must create one for each subcase in the solution.	Design constraints in design sensitivity analysisCreate a design constraint for a design sensitivity analysis
3.	Create a design variable.	Each design variable lets you vary a particular quantity, such as the model's physical, composite, material, or connectivity property.You can add design variables only to a solution, not a subcase.	Design variablesCreate a design variable for a design sensitivity analysis
4.	Solve the model.	The software computes the effect of changes in the design variable on the design constraint.	Solve the model
5.	Plot the DSA results.	Using the Scenario Based Data-Visualization Navigator, you can examine the design sensitivity analysis results.	Plot the design sensitivity analysis results
