Margin of safety workflow

This workflow represents a typical margin of safety solution where the results are obtained from a SOL 101 linear static analysis and built-in methods are uses for the margin of safety calculations.

Step	Step detail	Detailed help topics
1.	Create the FEM and Simulation	In the New FEM and Simulation dialog box, set the solver to Simcenter Nastran or MSC Nastran and the analysis type to Structural.	Create new FEM and Simulation files
2.	Specify the Nastran solution	In the Solution dialog box, select the SOL 101 solution type.	SOL 101 setup for margin of safety
3.	Construct the FE model	Define the material properties, meshes, and so on as you would for any other structural solution.	MaterialsMeshing
4.	Create the subcases	In the Simulation Navigator, right-click the solution node and choose New Subcase.	Create or modify a solution step or subcase
5.	Create the loads and constraints	For a SOL 101 Linear Statics - Subcase Constraints solution type, in each subcase create the loads and constraints.For a SOL 101 Linear Statics - Global Constraints solution type, in each subcase create the loads and above the subcase level create the constraints.	SOL 101 setup for margin of safetyBoundary conditions
6.	Create contact and glue	Above the subcase level, create contact and glue.Note: When the model includes contact, as a best practice, initialize the contact status for each subcase. To do so, edit the global contact parameters and change the contact status to Start from Initial.	SOL 101 setup for margin of safetyContact and glue conditions
7.	Edit the output requests	Margin of safety calculations may require results that the solver does not output by default. If you are using such a calculation, you must edit the solver output requests so that they produce the required results.	SOL 101 setup for margin of safetyRequesting output for Nastran analyses
8.	Solve the linear static model	The Solution Monitor contains information about the status of your solution, and the Nastran .op2 file contains the requested results from your analysis.	Solve the model
9.	Create the margin of safety solution	In the Simulation Navigator, right-click the simulation node and choose New Solution Process→Margin of Safety.	Create a margin of safety solution
10.	Create the load case sets	In the Simulation Navigator, right-click Load Case Sets and choose Add Load Case Set.	Load case sets (margin of safety)Create a load case set for a margin of safety calculation
11.	Create the margin of safety calculations	In the Simulation Navigator, right-click Calculations and choose Create Calculation.	Margin of safety calculationsCreate a margin of safety calculation
12.	Solve the margin of safety solution	In the Simulation Navigator, right-click the margin of safety solution node and choose Solve All Calculations.Upon successful completion, in the Simulation Navigator, in the Status column, Success appears.
13.	Review the margin of safety results	In the Simulation Navigator, right-click the margin of safety solution node and choose Display Results.	Margin of safety results
